/etc/extensions/, /run/extensions/ and /var/lib/extensions/ can have a named extension that treats the contained directory as "/".
For example /var/lib/extensions/example/usr/local/myfile" would be automatically overlayed as "/usr/local/myfile". It would be helpful if selinux automatically treated /var/lib/extensions/example as similar to / so a restorecon would set the right selinux labels for /usr/local/myfile.
There is a similar set of paths for confext - /run/confexts/, /var/lib/confexts/, /usr/lib/confexts/ and /usr/local/lib/confexts/.
There are also directories where mutibility changes are stored.
