[gentoo-user] Freeing up disk space problem!!

[trevor donahue]

Hi everyone,
I'm experiencing a major problem right now. I've been using gentoo for
several months now and I simply lllooove it!
So here's the thing. When I use gentoo for a long time, even without
updating the current pack of installed software (emerge -uD world), I am
left without disk space... In situations like this I start deleting
/var/tmp/*, /tmp/*, /usr/portage/distfiles/*, maybe do even a
revdep-rebuild to fix something, but even then I'm left with no more then
100 mb, which obviously is not enough ...
So this time I googled a bit and I deleted all the /usr/share/doc/ and this
left me with 2.5 gb of space (wow).

So the questions are ... in cases like this, what should be done? what is
storing this much space? logs?
