So maybe for each whitelist entry that is mounted on its own partition, recursively do the backup, so if we are saving /var/foo and /var/bar, they end up in /var/previous/foo and /var/previous/bar if /var is mounted separately. -- miʃel salim • http://hircus.jaiku.com/ IUCS • msalim@xxxxxxxxxxxxxx Fedora • salimma@xxxxxxxxxxxxxxxxx MacPorts • hircus@xxxxxxxxxxxx -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
