Looks good, but is there some stickyness of the setting? My use case is
schroot and it always starts with an empty upperdir when I create a
temporary/throw-away chroot but if I reboot the machine, then it's possible
that schroot will remount the overlayfs with a non-empty upperdir
(the temporary chroot is preserved until I explicitly end the chroot).

Cheers,
