No. All is readily prepared by the debian-cd project. Just copy the ISO plainly onto whole-disk device. (If you can't get a large USB stick, try with DVD-1 or netinst CD. The boot sector and partition table stuff is the same.) Have a nice day :) Thomas

It's like duck typing: if it has syscalls like cp and uses them like cp then it must be cp... at least something like that. In the end, dd gives you more control (buffer sizes, IO synchronization behavior for data/metadata) and it can print the status with SIGUSR1. But for regular "push data around from FD to FD" job the only crucial difference I remember is the nasty behavior of dd when a short read occurres - aborting instead of retrying as cp does. Not sure whether they changed the default mode to blocking mode nowadays. Regards, Eduard. -- <towo> Du solltest wissen: Du bist hier im Internet.

I saw it padding up short blocks and going on when i was
still on SuSE 10. This happened when reading from pipes with
slowly trickling data output.
Jessie's dd seems to be quite ok, though
$ for i in 0 1 2 3 4 ; do echo bla ; sleep 1 ; done >fifo
and
$ dd if=fifo bs=1024 >/tmp/dd_output
0+5 records in
0+5 records out
20 bytes (20 B) copied, 5.00444 s, 0.0 kB/s
yields exactly 20 bytes in /tmp/dd_output. Not 5 KiB or 4 bytes.
(It seems not to block but rather read on after each of
the 4-byte lines arrived. 5 reads. 20 bytes.)
The power of dd shows with commands like
dd if=/dev/zero conv=notrunc bs=1 seek=446 count=1 \
of=debian-8.2.0-amd64-BD-1.iso
which zeros the "bootable/active" flag of MBR partition 1.
Have a nice day :)
Thomas

Well... if you cp the image to the _device file_ it amounts practically to dd (but in dd you can set the block size and block count; I once experimented with block size dd'ing to an USB stick and seem to remember that there was a (speed-wise) "sweet spot" around 16K, but don't ask me whether this was inherent in the USB stick or depended on whatever other system parameters and planet alignments out there). Cat is also good. Again, to the device file. Make sure the "USB stick is not mounted" (in all three cases). Sometimes, overly helpful systems will mount the thing as soon as you insert it [2]. Unmount it before. Now when you cp the image file to the "mounted USB stick" [1] the result will be much different and most probably not the desired one. [1] Yeah, I know I'm fuzzing it. Precisely that would mean "cp the image file to a mounted file system which resides in the USB stick (phew)" [2] As long as there is a recognizable file system on it (see [1]). Otherwise the helpful system might react somewhat confused.

Also, how significant are the advantages in speed with an isohybrid image? A second or two perhaps on every 500M. There is nothing wrong with using dd but its versatility doesn't get employed for the simple job that cp and cat do equally as well.

For those who want to try this, the size of the Iso I got from the Jigdo build far exceeds a 16GB stick. It's reported as 20.9GB. I suppose I'll have to use one of my prized 32GB USB3 thumbdrives for this test.

How would I know for sure if it's ISO hybrid, and how would it fit on a standard 16GB drive? Guess it wouldn't, unless there was a great deal of extra space appended at the time the thing was created which could be truncated/removed. Actually, I strongly suspect that's true because the temp file that was created as soon as the process started was expanded to 20.9GB and never changed, so it's probably full of a lot of 0's toward the end.

Yes, the ISO is good. fdisk shows everything's fine. I'll have to try this with one of my 32's just to see it work. If it does, I'll be quite chuffed.

Looking at http://cdimage.debian.org/cdimage/weekly-builds/amd64/jigdo-dlbd/ it seems that the full set of software available from Debian for amd64 fits on two dual-layer Bluray disks. According to Wikipedia a dlbd disk holds 50GB, so you may need a couple of 64GB Flash drives before you’re done. Have fun!

Hi,
Steve Matzura wrote:
> How would I know for sure if it's ISO hybrid,
A strong indication is the presence of partitions when inquired
by program fdisk.
$ /sbin/fdisk -l debian-8.2.0-amd64-BD-1.iso
...
debian-8.2.0-amd64-BD-1.iso1 * 0 43859651 ...
...
You may let xorriso report
$ xorriso -indev debian-8.2.0-amd64-BD-1.iso -toc 2>&1 | \
grep '^Boot record :'
Depending on the version you will get
Boot record : El Torito , ISOLINUX boot image capable of isohybrid
or
Boot record : El Torito , ISOLINUX isohybrid MBR pointing to boot image
or
Boot record : El Torito , MBR isohybrid cyl-align-off GPT APM
The first message (from xorriso-1.2.2) indicates isohybrid only if
fdisk reports about partitions in the ISO.
The younger versions 1.3.2 (Debian stable) and 1.4.2 (Sid) can
tell without help by others.
xorriso-1.4.2 can list the whole boot equipment
$ xorriso -indev debian-8.2.0-amd64-BD-1.iso \
-report_system_area plain -report_el_torito plain
which will report
...

> and how would it fit on a standard 16GB drive?
It would not. If you cut of the tail you will get i/o errors when
files shall be read which are stored in the cut-off part.
The files are not sorted by importance or popularity in the ISO.

No. It is packed full with compressed .deb files (and a few others).
In the beginning of Jigdo download the 20+ GB mainly consists of holes,
indeed. But the dowloading of .deb files fills each of the holes.
Jigdo = Jigsaw puzzle Download
The .template file is like the wooden frame for a kindergarten jigsaw toy.
The .deb files (and some others) are the wooden blocks which fit into
the holes.
The .jigdo file substitutes for the toddler's brain.

And the net-install CD gets its packages from the Internet and sets up your sources list to do the same, so you can complete your installation in one fell sweep. Yes, you need an Internet connection so it is not suitable for all cases, but an Internet connection does not appear to be the problem here. Lisi

The installers on a netinst ISO and DVD-1 are basically identical.

Huh? the sources list is different if you use DVD's than if you use a debian mirror off the net. Even I, understood that much. -- "If you're not careful, the newspapers will have you hating the people who are being oppressed, and loving the people who are doing the oppressing." --- Malcolm X

Even I, understood that much. My claim is that the installers on a netinst ISO and DVD-1 are basically identical (they do the same job), not that a netinst ISO and DVD-1 are identical. That is because they are based on the same source. Explaining what this "sources list" is might clarify things.
