Is it safe to just remove files from /var/cache on a running system, or is
there a correct procedure for doing that?

Mine has hit over 3 gigs, making it one of the larger directories in /,
which is running low on space. I've hit all the low-hanging fruit I can
find and now I come to things like /var/cache, and I don't know what to do
about such.

Thanks in advance!
