Subject: [PATCH] tar-in: Add workaround because tar doesn't restore
|
|
capabilities (RHBZ#1384241).
|
|
|
|
Current GNU tar does not restore all extended attributes. In
|
|
particular only user.* capabilities are restored (although all
|
|
are saved in the tarball).
|
|
|
|
To restore capabilities, SELinux security attributes, and other things
|
|
we need to use --xattrs-include=*
|
|
|
|
For further information on the tar bug, see:
|
|
https://bugzilla.redhat.com/show_bug.cgi?id=771927
|
|
|
|
(cherry picked from commit 6d0ab14b56743679638ead0829ff3131749ac59b)
