Change rootfs pinning mechnism
Change rootfs pinning mechnism

Chane pinning mechanism: Use $rootfs/lxc.hold instead of $rootfs.hold
(in case $rootfs is a mountpoint itself), but delete the file
immediately after creating it (but keep it open). This will keep the
root filesystem busy but does not leave any unnecessary files lying
around.
