On the creation side, something like the above would be useful.

makefs supports storing a tree's metadata in an .mtree file.  We could
obviate the need for those keywords if tar could be made to do the
same thing :)

I'm working on an unpriv'd installworld (where the meta data would go
to the .mtree file, and the files would go into a tree owned as the
user building).  Mostly it is a port from NetBSD, but having tar that
would respect this stuff would be great.  Bonus points if the tag in
mtree could be used as a file selector (either additively or
subtractively).
