I started with 1.4. Dang I'm getting old. It's one reason I would hate
to leave Gentoo.

I think I found that info somewhere before I installed. Plus, one could
ask someone on IRC too. If they have it on a separate partition, the
results of df would be good enough and quick.

That would work too. At the time, /var was recommended.

If someone told me they was going to do a install similar to mine,
without all the udev, init thingy and /usr confusion, I would give a lot
of info but also recommend this. Install onto a spare drive then run du
on /usr, /var and such. Take that information and create partitions on
the permanant OS drive then copy the install over. That way you have
the best possible info based on your own install and what you plan to use.
They would then have a nice and neat system. If they use LVM, they can
even enlarge/shrink things as needed. This could be very true
considering the talk of moving portage files around. Sounds like /var
may be about to grow.

No problem there. If folks could put info on a wiki, it would be nice.
Example, 'I have KDE, Fluxbox, and this is the space required xxxx
Gbs.' Or 'I have Fluxbox and apache installed and I use xxxxGbs.' Then
list what /usr, /var and others are in Gbs. That would save some people
from having to redo their drives. Let the docs point to that for the
ones interested.
What a wish list. ;-)
