Thanks for that research, Paul.

I agree that the Apple products are harder to cross platform interface, but
I always find a solution, if I can actually _test_ it myself.

In the case of the Mac, I can't test it, so I'm severely constrained, but
there has been some new information on the Mac groups which may help.

Here is an informative verbatim quote on the Mac groups from moments ago...
  Message-ID: <0001HW.21568120001C68FE700003F812EF@news.eternal-september.org>
  Ubuntu will NOT be able to read/write HFS+ file systems if hfsprogs 
  is not installed, and hfsprogs is not installed as a default. 
  
  Users wishing to read/write HFS+ from Ubuntu must follow the 
  instructions at
 <https://askubuntu.com/questions/332315/how-to-read-and-write-hfs-journaled-external-hdd-in-ubuntu-without-access-to-os>

  There is no native methods for Ubuntu to read/write APFS. 
 <https://askubuntu.com/questions/991695/is-it-possible-to-mount-apfs-apples-newest-file-system-in-ubuntu-17-10>

  Paragon Software has an add-on extension which can do it.

Hi Aragorn and Paul,
Would you (and others) kindly look over this unfinished untested compilation 
I created this morning which I cannot test (I don't have a Mac), but which 
comes from reliable references you & Paul & Wolffan helpfully provided?

****************************************************************************
How to read & write to HFS+ partitions by booting to Ubuntu (on the Mac)
 !!!WIP ... Untested! ... Preliminary - for review!!!

Please improve so that everyone benefits from every action by each of us.
****************************************************************************
============================================================================
Your choice (works both ways):
a. Journaling disabled
b. Journaling enabled
============================================================================
Read/Write access to a non-journaled HFS+ drive.

1. Plug in the external HFS+ non-journeled drive into Ubuntu.
2. Ubuntu mounts the HFS+ drive automatically as read-only.
   $ mount -l 
     Your HFS+ device should show up as /dev/sdx 
   If the drive doesn't automatically mount, mount the HFS+ drive:
   $ sudo mount -t hfsplus -o force,rw /dev/sdx# /media/mntpoint
3. Click the eject button in file explorer to unmount the drive.
4. Install hfsprogs.
   $ sudo apt-get install hfsprogs
5. Optional: Check the drive.
   $ sudo fsck.hfsplus /dev/sdXY 
6. Click on the drive in the file explorer to remount the drive as r/w:
   Note: To manually remount the HFS+ drive:
   $ sudo mount -t hfsplus -o remount,force,rw /dev/sdx# /mount/point
============================================================================
Read/Write access to a journaled HFS+ drive.

1. Plug in the external HFS+ non-journeled drive into Ubuntu.
2. Ubuntu mounts the HFS+ drive automatically as read-only.
   $ mount -l 
     Your HFS+ device should show up as /dev/sdx 
   If the drive doesn't automatically mount, mount the HFS+ drive:
   $ sudo mount -t hfsplus -o force,rw /dev/sdx# /media/mntpoint
3. Click the eject button in file explorer to unmount the drive.
4. Install hfsprogs.
   $ sudo apt-get install hfsprogs
5. Optional: Check the drive.
   $ sudo fsck.hfsplus -f /dev/sdXY 
6. Click on the drive in the file explorer to remount the drive as r/w:
   Note: To manually remount the HFS+ drive:
   $ sudo mount -t hfsplus -o remount,force,rw /dev/sdx# /mount/point
============================================================================
To read/write on the Mac users' home folder, simply match the User ID:

1. On OS/X, check your UID (typically the default is UID 501):
   OS/X: System Preferences > your username > Advanced Options

2. Boot into Ubuntu & add a temp user of the same UID as found above:
   $ sudo useradd -d /home/tempuser -m -s /bin/bash -G admin tempuser
   $ sudo passwd tempuser
   $ sudo usermod --uid 501 yourusername
   $ sudo chown -R 501:yourusername /home/yourusername

   You can now read & write to both your Mac and Linux user's home folder, 
   no matter which OS you're logged into.

3. Optionally, add the new user of UID 501 to the Ubuntu login screen:
   By default, Ubuntu doesn't list users of UID less than 1000 on the 
   login screen, where this command changes that default value:

   $ gksudo gedit /etc/login.defs 
     Simply change the value of UID_MIN from 1000 to 501
============================================================================
To turn off HFS+ journaling from the Mac

1. Boot into OS X and fire up the Disk Utility. 
2. Click on your HFS partition, hold the Option key, and click File
3. A new option to Disable Journaling will come up in the menu. 
4. When you reboot to Linux, it will mount the HFS+ drive r/w automatically
============================================================================
To turn off HFS+ journaling from within Ubuntu

1. Compile disable_journal.c to disable_journal.out
   $ gcc -o disable_journal disable_journal.c
2. Run the program to disable journaling.
   $ sudo ./disable_journal.out /dev/sdXX
   where /dev/sdXX is the partition you wish to mount.
3. Then mount the HFS+ drive using the following:
   $ sudo mount -t hfsplus -o rw,user /dev/sdXX /media/hfspart

While the rest of your instructions seems okay at first glance, I'm 
afraid I don't speak C, so I'm going to have to defer to someone who 
does. :)

Thanks for looking it over Aragorn, where I'm all about working together.
(It's sad we have to waste half a thread dealing with worthless trolls.)

As you noted, and as always, no one person knows everything, but, together,
we're all far more powerful than we are alone.

In this case, I can't compile either, nor do I have a Mac, but with your
help, and that of Paul, Mike Easter, and Wolffan, it seems like we have the
problem (ostensibly) resolved such that this seems to be our new-found
capabilities:
1. We can boot our original Mac or Windows desktop to Ubuntu 18.04
2. Then we can connect *any* iOS device on the planet for full r/w access
3. We can also connect any Android device for even better full r/w access
4. Likely we can connect any USB drive or camera also (as an aside)
5. With simultaneous full r/w access to the original desktop filesystem!

All without installing _anything_ non-native on any of the systems above,
with the exception of the easily installed open-source freeware hfsprogs
for writing to the journaled Mac HFS+ file system.

I hope others, who know far more than I do, will look over (and hopefully
test!) the compilation so that we can hone it for everyone to benefit in
the future in our tribal archives (where I set up the tinyurl myself, many
years ago):

I generally try staying away from flame fests these days, and even when 
it is I who is the target ─ in which case it's usually not about 
GNU/Linux ─ I generally won't waste more than two posts explaining 
myself.

Disagreements will always arise.  Misunderstandings are a thing of the 
human species, and especially with the limitations of language.  
Language can be ambiguous, and well-intended hyperbole can often be 
construed as literal, which I believe to have been the case here.

One of the many beautiful things about Free & Open Source Software is 
that there is such a huge variety of tools available.  Many of those 
tools are written by people who were simply trying to scratch their own 
itch, and who then thought, "Oh well, why not let others have access to 
this as well?", and who then publish their code on things like GitHub or 
SourceForge.

And another beautiful thing is that this FLOSS code will then often be 
of much higher quality than any existing proprietary code that does the 
same thing.  Take Samba as an example.  A GNU/Linux or other UNIX 
machine with the Samba server installed actually does a better job at 
mimicking a Microsoft Windows server than Microsoft Windows itself. ;)

First, and foremost, Aragorn, thank you for always acting like an adult.
As you're aware, it's a thankless struggle to rein in the worthless trolls

As you noted, I explained that 
a) I strive to add new value in every post, and, 
b) I strategically & tactically confront trolls in threads I care about 
which *add value* to our overall tribal knowledge.

The problem I found out when I explain my strategy is that the proven 
value-less trolls who have no shred of decency left (e.g., Cybe R. Wizard, 
Wolf K, Frank Slootweg, Wildman, Danny DeVito, & especially Rene 
Lanontagne), literally feel that my confronting them on their trolling is a 
"challenge" for them to "step up to".

They don't like themselves, nor what they post (which adds zero value).
But worse - they don't like their own posts proving they add zero value.
*Even worse, they feel they have the God-given _right_ to troll!*

Hence, time and again, they need to *prove* that they have every right to 
shit on the potluck picnic that is Usenet... so, as you see in this very 
thread, they proved that, yet again, their God-given right to troll.

Sigh.

While those trolls have no shred of decency, there are other common 
value-less trolls who (thank God) still have a shred of decency left, such 
as Dan Purgert & Rudy Wieser, for example, who still retain a modicum of 
intelligence which enables them to comprehend the strategy of funneling 
them into acting like adults and, as a result, to accede to human decency, 
as adults.

But the likes of Cybe R. Wizard, and especially Rene Lamontagne, have lost 
any shred of decency that they may have ever had (which they proved in this 
very thread) - where they refuse to accede to any overt attempt to funnel 
them into acting like adults.

Hence, I will follow your advice and ignore the trolls (who usually pollute 
9/10ths of every thread), since the morons (most likely socks given the 
header information and overall pattern of prior posting) are coming out in 
force trying to assert their "freedom of the seas" God-given right to troll 
any thread they please.

> Disagreements will always arise. 

No. This isn't about disagreement. 
Seriously.

Adults handle disagreement on facts and positions easily.
Adults are funny that way.

I'm of average intelligence so I comprehend _everything_ written in this 
thread, where, I don't see any disagreement whatsoever. 

Do you?

If so...where do you see adult disagreement on the technical topic at hand, 
which is clearly cross-platform Ubuntu/Mac/iOS connectivity issues?


> Misunderstandings are a thing of the

I disagree that this is happening in this thread.
While your statement is a truism, in this thread, I don't see any technical 
disagreement whatsoever with the adults who are participating:

These are the only 4 adults on this thread to date:
a. You, Aragorn (who advanced our knowledge as adults tend to do)
b. Me, currently Arlen Holder (I switch headers over time for privacy)
c. Paul (who, I must applaud, is a model of restraint & compassion)
d. Mike Easter (who, like Paul, advanced our knowledge, as adults do)

The negative-value children on this thread outnumber us 6 to 4:
a. *Rene Lamontagne* (infamous on Windows groups as a worthless troll)
b. *Cybe R. Wizard* (just as infamous as a troll on the linux groups)
c. Dan Purgert (who, I think, retained some of his decency & restraint)
d. Rudy Wieser (who also, I think, "can" retain a modicum of adult decency)
e. Danny DeVito (who generally doesn't come up as a common troll)
f. Wildman (who generally doesn't strike me as a worthless troll)

I don't have to prove these 6 are trolls, as their own posts prove it.

Of those 6, I've dealt with the first 4 many times, so I know them well.
The first 2 prove worthless children, stunted in their mental capacity.
The next 2 are decent guys - but they still shit on the table nonetheless.
The last 2 I don't really know well enough to characterize yet.

NOTE: It's not unlikely that some trolls above are socks of others.

> Language can be ambiguous, and well-intended hyperbole can often be

In this case, nobody is disagreeing with the language, so, while your trism 
is a platitude, pseudo meaningful statements don't explain the actual 
dynamic.

What's happening here is that there are two classes of trolls (in this 
thread) where the second class (Dan and Rudy, both of whom I know well), 
seem to have retained enough adult decency to stop trolling when called out 
on it, while the first class (e.g., Rene Lamontagne and Cybe R. Wizard, 
both of whom I know all too well) are literally affronted that their "right 
to troll" was being challenged.

Thank you for understanding the *immense* strength that we adults, 
together, have. 

For example, I can ask a basic question based lack of real-world 
Mac-to-Ubuntu 'experience', and get an answer from, in this case, Mike 
Easter, who didn't actually have the real-world Mac-to-Unix experience I 
was seeking, but who gave me a great pointer. 

Later, you, and Paul and Wolffran (on the Mac) group provided more 
pointers, which I read, comprehended (for the most part), and *compiled* 
into a nascent tutorial, combining elements from more than a half-dozen 
separate references.

In the past, such things have often "snowballed" (as did the initial VPN 
discussion with Marek, if you remember those), into an entire working 
system, where, together, the adults on this newsgroup move our tribal 
knowledge forward, in increasingly monumental steps.

At the moment, for example, we have a proposed system which:
a. Uses _any_ consumer desktop OS on the planet (Mac, Linux, Windows)
b. Mounts r/w any consumer mobile device on the planet (iOS, Android)

This is a *big deal*.
In fact, it's a classic holy grail of cross-platform interoperabillity.

And we did it in just days with only the minds & efforts of five adults!
1. Mike Easter
2. Paul
3. Wolffan
4. You
5. Me

The rest simply polluted the conversation with their worthless drivel.

As can be expected, the Apple babies are all shitting on the picnic table, 
saying that the Ubuntu GUI is "terrible", so I need to ask one question 
which I'm confused about, but which "seems possible".

Do you think we could boot to the Mac (so we use the Mac GUI) and access 
the Linux partition of a dual boot Mac/Ubuntu desktop?

HINT: I know my Windows/Ubuntu dual boot only works in one direction, which 
is that Ubuntu easily mounts Windows filesystem, but Windows does not mount 
the Ubuntu filesystem.

Does anyone here know, offhand, if the Mac can mount the Ubuntu filesystem?

That's a key question because Apple users _hate_ the Ubuntu "GUI".

I cannot say this for certain, but with the caveat that the answer may 
be more convoluted than you might suspect.

The thing is that GNU/Linux supports multiple filesystem types as 
"native", by which I mean that they are filesystem types upon which you 
can install (and from which you can run) a GNU/Linux system without any 
problems at all.  

These are the filesystem types that are all supported by the upstream 
Linux kernel as suitable for installing a GNU/Linux system on:

  - ext2 (deprecated, but still functional)
  - ext3
  - ext4
  - btrfs
  - reiserfs (i.e. version 3 ─ reiser4 is not natively supported)
  - XFS
  - JFS
  - F2FS

Now, to the best of my knowledge, Ubuntu does allow one to choose what 
partitioning layout and what filesystems to use during installation, but 
I don't know what the default filesystem choice would be if the user 
doesn't specify anything consciously.  I suspect that it would be ext4, 
but it could just as easily be btrfs these days.  

btrfs is essentially a GPL-licensed rewrite of the ZFS filesystem that 
is native to Solaris, OpenIndiana and FreeBSD.  Like ZFS, btrfs is a 
combined filesystem and volume manager.  It allows one to create dynamic 
subvolumes within a single larger volume, and it supports copy-on-write 
and native RAID functionality.

What I can tell you is that there is a driver for Microsoft Windows ─ 
not included in the Windows system itself natively, but freely 
downloadable from the internet nevertheless ─ for ext2/3/4.  What I do 
NOT know is whether macOS has a similar driver available, nor what other 
filesystems it supports besides the Apple-specific filesystems and 
perhaps FAT/FAT32/exFAT.

> HINT: I know my Windows/Ubuntu dual boot only works in one direction,

See above; there is a Windows driver available for mounting ext4, but 
it's not included by default in Microsoft Windows.

> Does anyone here know, offhand, if the Mac can mount the Ubuntu
> filesystem?

I suspect not, but there may be an external macOS driver available that 
does this ─ or at least, on account of ext4.

What's strange though is that industry-standard POSIX filesystems like 
XFS and JFS are not natively supported in macOS.  

ext4 is specific to the Linux kernel, but XFS and JFS are industry 
standards in the UNIX world, and macOS is being marketed as a certified 
UNIX.  So one would expect macOS to support those filesystems, but it 
doesn't.

Odd...

LTS versions 14.04, 16.04, and 18.04 have all defaulted to ext4.  I
imagine the non-lts versions do the same, but I don't ever use them.
btrfs is gaining popularity, but as of yet hasn't taken over as "the
default".

Quick google came up with this article[1] from 2014.  Given it's the
first hit for "macos filesystem support"; I imagine it's still an
accurate represenation of the state of things.

Short version is -> native support is HFS+, FAT32, or exFAT (all rw); or
ro for NTFS.  You can get additional drivers for NTFS (ntfs-3g), ext2/3,
or sshfs.  

I would imagine that in the intervening time, the ext2/3 driver has also
added support for ext4.

Good point on the various filesystems.

I was remiss in not remarking that I am only asking about default
filesystems, at first, where only if the native OS's default filesystem
*needs* to be changed, do any of the other filesystems begin to matter.

Hence, only two filesystems initially matter for the original question:
a. The Mac default file system (apparently HFS+ with journaling?)
b. The Ubuntu default file system (apparently ext4?)

Well, whatever the *default* is, is what the question is about. :)

That's the logical approach, since I'm trying to come up with a general
approach, where the first step of any general approach is normally to
assume default values.

If btrfs is not the default filesystem for Ubuntu 18.04, then it won't
matter for this question, but it's good to know nonetheless.

Ooooooh... that's good to know!

Thanks. (Note to self: I should explore that separately.)

What that means is that it's possible to *boot to Windows* and obtain the
partial cross-platform functionality that booting to Ubuntu gives us.
a. It would give us simultaneous access between Windows & Android & Linux
b. But it would still not give us read/write access to iOS files

Yesterday morning, when I first read the referenced articles, I wasn't
looking for the Mac to read the Ubuntu default file system; it was just
when the Mac users complained that they thought the Ubuntu GUI horrid that
the amelioration solution of the Mac reading Linux filesystems came to
mind.

I'm all about solving users' objections, if/when they're real.

Thanks for that pointer which I wasn't aware of until you suggested it.
It seems there is a _lot_ of information about that, so it's not a problem.
<https://thelinuxcode.com/mount-linux-partition-ext4-ext3-ext2-windows-10-8-7/>

The main reason this idea is not all that useful here, is that booting to
Windows doesn't give the access to iOS that booting to Ubuntu does.

But it does give access to everything else (other than HFS+ and iOS), so
it's useful for most people who don't have Apple devices to deal with.

Googling, apparently commercial solutions exist:
 <https://apple.stackexchange.com/questions/29842/how-can-i-mount-an-ext4-file-system-on-os-x>
 <https://www.paragon-software.com/home/extfs-mac/>

But apparently, at least upon initial inspection, some say it's not FOSS:
 <https://www.linuxquestions.org/questions/linux-general-1/mac-driver-for-the-ext4-file-format-787407/>

But, maybe it is, since the OSXFuse product is FOSS and said to work fine:
 <http://osxdaily.com/2014/03/20/mount-ext-linux-file-system-mac/>

The actual Mac OS version may or may not be an issue though:

It "seems", upon initial inspection, that a FOSS solution "probably" exists
such that the MacOS likely "can" read the default Ubuntu file system.

Even so, and oddly so, the Mac still can't read iOS as well as Ubuntu does
(AFAIK), so, it's only a partial solution to ameliorate those who claim (on
the Mac groups) that "the Ubuntu GUI is terrible".

Hi Aragorn,
Just as an FYI to add to the tribal knowledge, I simultaneously installed
all three of those Windows Linux filesystem readers/writers (yes, I know,
that might not be a good idea to have all 3 running simultaneously).

1. <https://sourceforge.net/projects/ext2read/files/latest/download>
2. <https://sourceforge.net/projects/ext2fsd/files/latest/download>
3. <https://www.diskinternals.com/download/Linux_Reader.exe>

*ext2read*
The first is just an executable, while the latter two are installers.
That first executable has to be run as Administrator; the rest don't.
Even so, for whatever reason, I couldn't find my Linux home files.

*ext2fsd*
This automatically creates a drive letter for your Linux filesystem.
The GUI was kind of miserable (e.g., it wouldn't even resize properly).
I'm sure it can do the stated task, but it has a steep learning curve.

*LinuxReader*
I kind of like the GUI of the last one the best, at least upon 1st use.
It presents your Linux and Windows disks in a familiar "My Computer" style.
When you want to copy a file from Linux to Windows, you just hit "Save".

Since the price of freeware is the effort it takes to find the best ones,
my quick test clearly tells me to spend time on the "LinuxReader" and to
ditch the other two (unless there's a reason I learn later to do
otherwise).

Thanks for letting me know these three programs exist, as you save me
umpteen reboots, just to access files that are on the Linux partitions!

NOTE: As per my discussion with Aragorn, I will only respond in this thread
to those those adults who intend to further our combined capabilities.

Here's a graphic which shows that ext2read can easily see the "root"
directories of the Linux system, but not anyhing inside the home directory,
of which there are plenty of files that ext2read doesn't seem to see.
 <http://www.bild.me/bild.php?file=8343685sda5.jpg>

Luckily, LinuxReader easily sees inside the home directory, by default.

I'm not sure if there is some magical setting to ext2read that allows it to
see inside the home directories (maybe it's a UID permission issue?).

Dunno - but LinuxReader is working fine, by default.

I'm guessing that it _may_ be due to /home being a mountpoint for 
another filesystem.  In that case, the ext2read tool might have a 
problem knowing what filesystem to mount at /home, and with nothing 
mounted there, /home would indeed appear to be empty.

Another option _may_ be that the ext2read tool cannot handle dot files 
properly, although that seems odd to me, given that even the NTFS 
filesystem used natively in Microsoft Windows supports dot files ─ but 
FAT did not, of course.

Mind you, the above is just conjecture on my part, as I don't do 
Microsoft Windows, and therefore I have no way of testing these Windows-
specific tools.  Setting up a virtual machine with Microsoft Windows is 
also not an option, as I am working from a refurbished computer with 
only 3.3 GiB of RAM and a fairly slow Athlon64 dual-core processor.

You don't need a lot of RAM to run it. I could
probably run a half dozen of these. The machine in
this picture is like yours and reports "3.2GB free".
The machine I'm typing on, doesn't make OSes
this bad all that usable. It took a long time
to get this picture (get machine to settle down).

If I run the Guest on my other machine, it's got
the resources to make the VM usable (even though
the VM is a pig).

This is the Guest using Linux Hosting. The /tmp

Assuming it is a mountpoint for another partition / filesystem, it is
also possible that it is not ext2/3/4.  However, given we know nothing
of the filesystem(s) in question; all we have is conjecture.

Hi Dan Purgert,
Paul mentioned on the Windows groups that it might be something like that,
or encryption, where NOTHING on my Ubuntu 18.04 is "not default".

That is, EVERYTHING is default as the Linux is there as a dual boot mostly
so that I can easily interface with all mobile devices and so that I can
run things that Windows can't easily do (grep, sed, sort, etc.) ... (at
least more easily than is setting up cygwin, bash shell, GNU coreutils,
etc., on Windows).

Here is the user's HOME directory showing up in *LinuxReader* on Windows:
 <http://www.bild.me/bild.php?file=8264301linuxreader.jpg>

I'm sure someone with experience using *ext2read* would know why it won't
show up anything inside the users' home directory - but - it's not a big
deal (unless I need 'write' permission - which - I think - LinuxReader
doesn't provide). 

I'm extremely familiar with freeware, where you learn what you need to
learn, so, right now, I don't need write permission from Windows in the
Linux hierarchy, so the LinuxReader is fine for copying.

NOTE: You use the "save" button to "copy", as shown in the screenshot.

That would be indicative that /home is the same partition as /, so more
likely that it's perhaps encryption rather than inability to find the
partition or read the filesystem (although one would imagine that an
encrypted $HOME would not be readable in either case -- or at least
require some additional "do xyz to decrypt").

Nothing I do is by accident, as I'm an old hand at Usenet.

There's a strategic and tactical reason when I use the full name, but it's
mostly when I'm funneling the people who have decency which means they
"can" be funneled ... so, I'll drop that tactic unless I need it again for
adult-funneling purposes.

Yeah, but ... if it was encrypted, I would know it, where ... rest assured,
I've been burned like you can't believe with that damn encryption in the
past.

As an aside that I'd rather not belabor, on CentOS, I foolishly acceded to
the request to "enable encryption", which, after a good six months of use,
corrupted itself, and rendered my entire home directory unusable to all but
the NSA (and maybe not even them).

As a result of that torture, I _hate_ encryption on Linux. Hate it. Despise
it. Deplore it. etc. It's clearly flaky (or at least it was ... this was
around 2010 days, as I recall). I'm sure I could dig up my threads from
those days, where I simply want to cry just thinking about the grief that
damn flaky encryption caused me.

Hence, rest assured, unless it encrypts itself, I'm never touching Linux
encryption ever again. 

Back to our story, I found two more potential solutions for the tribal
archives to benefit, which are:
*Ext4Explore*
 <https://sourceforge.net/projects/ext4explore/files/latest/download

And, surprisingly (albeit, quixotically), someone suggested that 7Zip could
access the Linux disks (which I tried, & failed at, at least initially):
  <http://www.bild.me/bild.php?file=56940667zip.png>

For commercial solutions, it seems Paragon is in this business too:
 <https://www.paragon-software.com/business/extfs-for-windows/>

As always, for others to benefit, here is a screenshot of a quick test
using *ext2fsd*, which I would characterize as having a somewhat
"non-intuitive" user interface.
 <http://www.bild.me/bild.php?file=2916654ext2fsd.jpg>

However, with ext2fsd, a lot may depend on the choices upon installation,
where I was presented with these defaults:
[x] Make Ext2Fsd automatically started when system boots [sic]
[x] Enable write support for Ext2 partitions
...[x] Enable force writing support on Ext3 partitions

By way of contrast, the user interface to *ext2read* was fine, but the
users' home directories showed up empty (for some strange reason):
 <http://www.bild.me/bild.php?file=8343685sda5.jpg> 

Meanwhile, the user interface to *LinuxReader* was the most intuitive (upon
first inspection anyway) and the users' home directories were visible:
 <http://www.bild.me/bild.php?file=8264301linuxreader.jpg>

The "problem" with LinuxReader might be that it's apparently read only.

As you're all well aware, the expense of freeware is almost all in the
choosing of the best ones, so my "added value" to the team is simply those
initial insights - where I ask for more insight from experienced users.

What name were you using before the twelfth of June?   If you were
recently married/divorced congratulations!

"Funelling" what do you mean by that?

Do you really consider one calling you out for obvious BS to be
childish?  Supply those ten thousand tutorials you claim to have
written.  Let's see that example of your own adulthood.

What's childish is to make such a statement without expecting someone
to call you on it.

C'mon, pony up with that (at least) list, although I'd prefer pointers
to some real tutorials (about, oh, I don't know, maybe 10,000).

Perhaps he meant he wanted us to killfile him? At the very least, others
who've already binned him would stop seeing us take the bait.
