You see, I have always had a separate /usr... never seen a problem yet.
Booting into "S" doesn't do the data discovery. That is what I am
getting at. "S" or "1" is maintenance mode. Everything you need to
maintain the boxen should be on "/" and that is all it should have. I
come from very heavy duty system, that they would get everything except
the root filesystem blotched out. Get massive upgrades "HOT" and then
I'd have to restore the filesystems. If I did not have everything I
needed to restore from a Remote Tape-Library... I was fscked. These
machine sometimes took hours to come up, with 32 Processors and 32GB of
Memory, Multiple Multi-terabyte filesystems (All with journal-ling)
Everything I needed was on /. Plus I could make a bootable tape or a
bootable CD or bootable DVD and still be inside (usually with frillz
added because I had room) 250MB. This was on AIX, HPUX, TRU64 (OSF/1),
etc...
So, now you understand why I always suggest 200MB(okay I have a 300MB /
filesystem).
> Why should /tmp be its own partition instead of symlinking /tmp -> /var/tmp?
/ and /var are machine critical. Let us remember I come from Huge
Enterprise setups. Let's just suppose You are a developer writing a
PL/SQL 300-way innerjoin. Those temporary files get written to /tmp.
With /tmp on "root" filesystem... oops there goes the machine
With /tmp on /var all logging goes away... among other things.
With /tmp its own filesystem... the PL/SQL fails "YEAH" that's what you
want.

Yes. Simplicity. I use grub as a boot-loader.
My workstation menu.lst looks like:

If I had it included in "/" I'd have to add /boot to the front of every
line.
Plus it keeps me from having toooo many kernels installed, plus I can
make it read-only making it more difficult to change.

It's fine... I have used spreadsheets to map out things and I never have
come up with the perfect setup. Close... but not poifec
