remove '/' /var/cache/packages

[slackjeff]

I'm trying to fix this! this is our first step to remove '/' //var/cache/packages (laughs)

[rworkman]

Here's the trouble: are we absolutely certain that this will not cause a problem when e.g. ROOT=/somewhere (i.e. not /) because someone is running slackpkg to operate on a chroot environment?

What about unsetting ROOT if / at the very beginning and then using ${ROOT}${ROOT:+/} instead of ${ROOT}/?

Not perfect because of subsequent ${TEMP}, though.
