You mentioned logfiles. I find it good practice to give essential
processes an explicit partition for logging and another one for data.
This way i can get away with relatively small system partitions.
And if you do syslog to a remote target, what else remains in local
logfiles.

Actually, When I said i was not after numbers, I meant I would like to
avoid the discussion if 1 or 2 or 20 gb are adequat. Of course the
perfect amount depends on how one is doing things. With the method i was
describing everyone can find out himself and adjust as needed.
