It also depends a lot on what you install.  When configuring a system
that's lacking in available disk, it's critical to carefully plan your
filesystem sizes.

For example, /usr occupies approx. 48MB - but requires about a 55MB
filesystem due to the 10% default free space requirement.  Plan
accordingly.

My general rule of thumb is close to Ollivier's.  20-25MB for /, and
55-60MB for /usr.  You would of course need to create an additional
filesystem (or size /usr appropriately) for user space.  You can get by 
with a 16MB /, but I absolutely would NOT recommend it.  This leaves
very little space for expansion in /tmp and /var, not to mention that
fact that it would make new kernel installation tricky.

I believe he's referring to the live filesystem CD that ships with
2.0.5.  If that's the case, then I can comment a bit on it as I've used
it.

You CAN save space using the second 2.0.5 CD (lfs).  I experimented with
this by using lndir (/cdrom/usr/X11R6/bin/lndir) to link all the files 
from /cdrom/usr to /usr on my disk.  This was after doing a minimal
install.

I wouldn't recommend running with this configuration unless you have a
fast CDROM drive, or unless you have lots of spare time.  I have
neither. :)  I suppose that leaving only rarely-used stuff on the CD is
an option.

Yup.  In fact, one of the first things I do after completing the
installation is make mount points for /usr/local, /usr/src, and
/usr/obj, and link /usr/tmp to /var/tmp (a few packages seem to want to
create temp files in /usr/tmp for some reason).  I then remount /usr
read-only and never worry about it again.
