rsync --delete

[Ken Chase]

problem is he's trying to rsync into the target dir and have the
side effect of delete. so an empty dir would necessarily need to be
in the target of course and thus created there, triggering the quota block.

he tried to avoid this by using device files then 'blocking all device files'
but i think rsync figures out first there's nothing to do, so it just stops
and doesnt do the delete. wonder if --delete-first would help there perhaps.

however, this is a REALLY obtuse way of running rm. unless of course he's
trying to inject some kinda options into a script that can only run rsync
or something wonky like that.

/kc
