Exactly Philip !!
Separate /home, /usr, /var etc.... make sense in a networked environment.
For example, consider a case where we have swap, /, /usr/, /home, /var.
Now i as a network admin will take great care about backing up /home (more
care than other backups :-) anyway). Infact i could have it on a different
harddisk (if i have so many users) or even another computer. I will mount
this /home everytime.
Now if i screw up my system (somehow) or i want to to a complete reinstall,
i unmount /home, replace my system and remount it again. Done !!
I saw a post telling to mount / as readonly from your prompt. I dont think
it is possible. Because, things are being written to /proc, /var/logs,
wtmp, utmp all the time. You will have to boot linux from a floppy and
mount the / partition on the harddisk as readonly to be able to do an fsck.

Another way to run fsck is to crash your system by just pressing the reset
switch which we are used to in windoze. Guaranteed fsck done !!!! ;-)

Subject: Re: [ILUG-BOM] Fsck
It's pretty much a fact what Amit has said that most people only create
two partitions. That's the way I started out. It makes sense to first do
a very simple installation to find out how things work. Once your
confident enough, you should format and reinstall. Of course, backup
whatever you have done in that short time.
I was kinda forced into reinstalling cause some wise guy in the office
kept switching off the machine without a proper shutdown. It finally came
to a point where the system would no keep running a fsck on every boot,
and I could not unmount properly.
I tarred/gzipped all files that I had changed, and ftp'ed the file to
another machine. Then deleted the / and swap partns and reinstalled.
I now have partitions for:
/, /boot, /home, /tmp, /usr, /usr/src, /var
Works pretty well, and I can keep certain partitions read only until I
actually have to change files there.
Finally, I restored my backups. That's where my next problem started.
I unknowingly restored my old fstab, so the next time I booted, I couldn't
do anything because my partition table did not reflect what was entered
into fstab. I could not change fstab because / was mounted read only, and
I couldn't remount it because the partition entries in fstab did not match
the partition table.
I could not figure out any solution after two days, and decided to
reinstall again. This time I restored correctly.
I have never lost any information because I always take backups and keep
them in varied locations that are really far apart.
Hope my experience will help anyone who wants to set up a new system.
Keep it simple to start with, get confident and then reinstall. Then
recompile the kernel.
