There was a bug in v44 where some mount points mounted by initscripts
(for instance /var/lib/nfs/rpc_pipefs in nfs initscript) which was
unmounted before initscripts were stopped but it was fixed during the
rewrite done for fstab-generator (I've extracted it as
https://build.opensuse.org/package/view_file?expand=1&file=fix-umount-order-at-shutdown.patch&package=systemd.openSUSE_12.2_Update&project=home%3Afcrozat%3Abranches%3AopenSUSE%3A12.2%3AUpdate )
