Makes it possible to clone and start a container whose ZFS subvols are not yet mounted for some reason. If a subvol cannot be mounted, there's a better error now: zfs error: cannot mount '/myzpool/subvol-103-disk-0': directory is not empty Previously, cloning would quietly do an "empty" clone, and startup would fail with: mount_autodev: 1074 Permission denied - Failed to create "/dev" directory lxc_setup: 3238 Failed to mount "/dev" do_start: 1224 Failed to setup container "103" __sync_wait: 41 An error occurred in another process (expected sequence number 5) Signed-off-by: Fabian Ebner <f.ebner@proxmox.com>
