I usually use 7GiB for / on stable, 7 GiB for / on rawhide, 2GiB for
SWAP and the rest for /home. For the system these 7GiB are just enough
(well, it's not enough for corner cases like when you install everything
and a kitchen sink, but Desktop users usually don't need that much). I'd
also say that for server stuff, people would usually create a
separate /var partition, so I don't really think this is a huge issue.
Just use 10GiB as a base and if you have big enough available space (say
more than ~100GiB) you can start increasing until you reach some
predefined maximum (I think ~30GiB would be sane). And when you have too
little of space (say less than ~20 GiB), don't split by default.

In short, I'd prefer to have as little as is needed for system (+ some
extra for future needs; i.e. for /) and as much as possible for data
(i.e. for /home and /var if either is separate).

I think debian has this problem pretty much solved, is there any reason
for not doing it the same way they do?
