[pve-devel] [PATCH pve-container 5/7] vzdump: exclude lost+found with unprivilged containers

The lost+found directory is created by mkfs and fsck with
the absolute numeric owner of 0:0 which causes tar on an
unprivileged container to error when trying to read it, so
it needs to be excluded un-anchored.
This doesn't need to be done for rsync as rsync runs as
privileged root.
