Yeah, I thought that was going to be the case.
I have a new server in implement into a big client and I want it to go first
time around not stuff around with figuring out what size should I allocate
for / and how much for /home and how much for /usr etc..
I calculated from our old SCO box what used how much in terms of development
stuff and goofed up that a "du -ks" didn't follow symbolic links and when
copying the old data to the new I ran out of space.
THEN, the programmers decided to explain to me what was where and how their
datbase worked after it was too late and I had create sym links to other
file systems. Hence my question.
The only real thing I could see would be a problem is if /tmp filled up do
to a stupid print job or something but otherwise it should be OK.
I guess your right about fsck too as they do take a while.
Thanks all for you info... I will partition it but it's just a matter of how
much to allocate for each partition..
thanks,

It's not crucial or anything like that, it's just a tradeoff.
If you toss everything in one large partition, then when you have to
fsck it, it takes ages. Plus the small chance a scrambled FS affecting
everything. On the other hand, all the free space is pooled.
If you separate filesystems, if one needs fscking it takes less time.
On the other hand if you run out of space on one FS, you may have lots
of space on other FS. If you export FS with NFS, it's slightly more
secure because you can just export /usr and /home for example.
If you have separate devices then you can get better performance by
spreading the FS.
