I could imagine vac/unvac not dealing with resource forks or POSIX extended
attributes and such properly, as well as potentially having difficulty with
symlinks, but having dealt with stuff like that in "xar", I don't think it's

I may need to read up on venti and see what sorts of data types it supports.
 Might be time to add some extensions?
