For binpkg, the approach I mentioned would remove the need to for tar |
| 9 |
to support xattrs- the same mechanism for the PM to tweak the perms |
| 10 |
would be usable. So no need for tar/bsdtar to restore xattrs- it's |
| 11 |
undesirable anyways since as I mentioned, if the cap couldn't be |
| 12 |
applied for whatever reason it would result in a chmod -s binary being |
| 13 |
installed. |

For src, I'd strongly be against restoration there. It just opens up |
| 16 |
way too many surprises- a simple example is a tarball carrying the |
| 17 |
immutable flag. Xattrs really should be specified by the ebuild (and |
| 18 |
applied by the PM) instead- far more controlled namely. |
