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. ~harring
