The FHS specification says that applications using /var/cache should expect
those data to disappear anytime, so under a strict interpretation it should
be safe to remove everything. Practically, though, I don't know that I'd
trust every application to adhere to that, so it might be worth looking at
what applications are the biggest users of the directory and making
targeted deletions or even application-specific tools to remove the data
(i.e. "yum clean all").
