In a freshly installed Debian, /etc/passwd sets the home directory for

Working routinely for about 93 days and I no longer bother to keep 
fingers crossed.  If reinstallation becomes necessary, tough luck.  
Just another chore.  

What I'm doing is similar to using DOS years ago; although DOS 
predates experience of most people reading now.  If login is used 
properly, root shouldn't be more vulnerable than any other account. 
You're welcome to probe my system.  If you find a vulnerability, a 
post will help or amuse more than me.

Incidentally, OpenBox is here with minimal graphics displayed.
Most programs start from a terminal.  Puppy is a nice system but 
the graphical interface is more than I want.

For years my data was on an SD card reformatted to ext3. When 
switching to a new SD about a month ago, I decided to leave the 
factory installed FAT file system.  No problems.  The FAT file system 
lacks permissions as in ext.

Motivation to leave FAT: authorities claim the factory format is 
optimized.

I think he might be too Greg. I'm 87, and largely bypassed dos on my way 
to linux in the 90's. We've come a long way, and if dos disappeared 
yesterday, I'd have bought a 6 pack for a mini-celebration last night. 
We're still trying to put up with its lack of features other filesystems 
have given us since.

You need to be very old to have used these machines indeed, but probably
not old enough to change the average age of a list with thousands of
subscribers all by yourself. :-Þ

Huh ? ... What ? ... Age ? ... Whom do you call old ?

VIC-20 users don't get old.

Since most of the posters here are of over average age we should immediately
drop the whole concept in order to avoid a severe mathematical paradox.

I never used the word "old".

I'm fairly sure that most of the *regular* posters here (the ones who
actually answer questions) are above the average age of Linux users as
a whole.  I feel like I'm one of the younger regulars, at merely 52.

For subscribers as a whole including lurkers... well, maybe I'd better
not try to guess.  Insufficient data.

And yes, I definitely remember DOS.

I remember *reading about* the KIM-I (and the Altair, and a few others) 
in electronics magazines; I started with a TRS-80 Model I myself (and 
with high school programming classes on an IBM 370/135 at the District 
Office, with terminals connected over a pair of multiplexed phone lines 
[and a maximum terminal speed of 300 Baud]).

Punch cards and an IBM 1620 at university.  The first computer I owned I
built using a Z80 SBC demo board. Cassette tape mass storage, modified
Selectric printer, OCLC crt terminal, homebrew OS.

I starting in college with punch cards an IBM 360 and a PDP 11/15 that 
actually let me sit at a terminal.  After I graduated I got a TRS 80 
Model III (Z80)  with cassette tape for mass storage and 16K of RAM.

I too started by learning Fortran on an IBM 360/44. We collected all
our punched cards and lineprinter paper and sold it to subsidise the
Christmas booze. We even kept the useless chad.

Our jobs were run at the end of the working day because we were only
borrowing the time from Theoretical Astronomy. It sat in its own
detached building.

We punched the JCL on special coloured cards. I think this was because
the punch was unspooled, so if your program failed to compile, the
operators needed to be able to see the end of your data cards, to
clear them out of the stack of jobs, so that the next could run.

When we moved to using the university's 370/165, which had a
self-serve high-speed card reader, we had people searching for
the coloured cards because they thought the reader wouldn't
read JCL from ordinary ones! (The card reader was spooled with
HASP, so it always gobbled up all your cards—until they started
to get dog-eared.)

I was fortunate in never using 8-bit micros at all. The first 16-bit
I played with (not mine) was the Naked Mini/LSI, but most of my work
was with the HP9845. It was far too expensive to own one; I recall the
maintanance contract on it was £1000 per year in the early 80s, which
would be more than £4000 today.

David.

Maybe, maybe not. I got started with a KIM-I: 6502 running at 1 MHz,
just over 1 kilobyte of RAM. Six seven segment displays and a hex
keyboard for data entry. I still have one.

See what you did: you started a nostalgia oneUpManship storm.

I'm not sure why you quoted this after three months without any
indication of its referent. What I didn't understand was why you
had to have /root under /home, and indeed, when you later revealed
your partition layout, it looked even less necessary, because you
have /root on a different partition.

I wouldn't expect one. There are a whole variety of home directories
specified in /etc/passwd.

I don't think the number of days has that much influence on whether
you'll get bitten, as the probability distribution is quite likely
to be memoryless. Unless, of course, you're noticing some of your
near-misses, and are becoming adept at avoiding or working around them.

That's right, and any old rogue TSR could crash the system, or any old
virus take it over. I ran DOS 3, 5 and 6.22 systems that were very
reliable, but only by restricting in the extreme what I ran on them.

But that doesn't inject any truth into your second statement, and
saying to use login "properly" just begs the question.

No thanks, that just makes me an agent of reckless acts.

(I didn't express a view on Puppy itself, only two passing references

Did you leave out "not"? From which half of the sentence?

Unless you're running your system from a FAT filesystem, I'm not
sure I see a connection between this and solving your earlier
permissions problems (which I admit I barely recollect).
