Correct in general, but this reply is on the ccache thing more than /tmp
and /var/tmp.

I had entirely forgotten the default ccache location, if I ever knew it in
the first place, as I added ccache and changed that setting very early in
my Gentoo setup, I believe before I had even completed the emerge
--emptytree system.  CCache has never been in the default location on my
box.  Originally, I had it as its own dedicated partition as well, but
when I did the reorganization for my RAID upgrade, I put it on a subdir of
4-way striped RAID-0 array partition, sharing the partition with similar
subdirs for /usr/src and the portage tree.  All three of those need no
redundancy as the contents are are easily redownloadable from the net or
in the case of ccache, regenerated automatically if destroyed, all three
tend to have many small files, so reiserfs is the perfect managment
strategy, and all three can benefit from the speed of the 4-way striped
RAID-0 as well, so it made sense to put them together on a shared
partition.
