For binpkg, the approach I mentioned would remove the need to for tar 
to support xattrs- the same mechanism for the PM to tweak the perms 
would be usable.  So no need for tar/bsdtar to restore xattrs- it's 
undesirable anyways since as I mentioned, if the cap couldn't be 
applied for whatever reason it would result in a chmod -s binary being 
installed.

For src, I'd strongly be against restoration there.  It just opens up 
way too many surprises- a simple example is a tarball carrying the 
immutable flag.  Xattrs really should be specified by the ebuild (and 
applied by the PM) instead- far more controlled namely.
