We're on the same page here.

I would also avoid putting ccache in /var/tmp for this reason.  I
suppose it is disposable but I'd think you'd want a different
retention policy than most stuff in /var/tmp.

In any case, ccache is only useful to the extent that you actually
re-use it, so purging it every time you reboot is usually
counterproductive, though it could be situational.
