Title: systemd fails to generate .device units inside LXD containers Status in systemd package in Ubuntu: Confirmed Bug description: See LXD issue here for more context: https://github.com/lxc/lxd/issues/3638 After attaching a block device (in my case /dev/sdc3) to a LXD container, the dev-sdc3.device unit is not generated. However, the dev-sdc3.mount unit is generated correctly. Steps to reproduce (from GitHub issue): stgraber@castiana:~$ truncate -s 10G test.img stgraber@castiana:~$ sudo losetup -f test.img stgraber@castiana:~$ sudo losetup -a /dev/loop1: [0022]:169383 (/var/lib/snapd/snaps/core_2381.snap) /dev/loop2: [0022]:770242 (/var/lib/snapd/snaps/core_2312.snap) /dev/loop0: [0022]:1170310 (/var/lib/snapd/snaps/core_2462.snap) /dev/loop3: [0045]:309158 (/home/stgraber/test.img) stgraber@castiana:~$ lxc launch ubuntu:16.04 issue3638 Creating issue3638 Starting issue3638 stgraber@castiana:~$ lxc config device add issue3638 sda unix-block source=/dev/loop3 path=/dev/sda Device sda added to issue3638 stgraber@castiana:~$ lxc exec issue3638 -- mkfs.ext4 /dev/sda mke2fs 1.42.13 (17-May-2015) Discarding device blocks: done Creating filesystem with 2621440 4k blocks and 655360 inodes Filesystem UUID: 77832ca2-b16d-4b94-8f7d-9ea08c5e6913 Superblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632 Allocating group tables: done Writing inode tables: done Creating journal (32768 blocks): done Writing superblocks and filesystem accounting information: done stgraber@castiana:~$ echo Y | sudo tee /sys/module/ext4/parameters/userns_mounts Y stgraber@castiana:~$ lxc exec issue3638 -- mount /dev/sda /mnt stgraber@castiana:~$ lxc exec issue3638 bash root@issue3638:~# echo "/dev/sda /mnt ext4 defaults 0 0" >> /etc/fstab root@issue3638:~# cat /etc/fstab LABEL=cloudimg-rootfs / ext4 defaults 0 0 /dev/sda /mnt ext4 defaults 0 0 root@issue3638:~# exit stgraber@castiana:~$ lxc exec issue3638 -- umount /mnt stgraber@castiana:~$ lxc exec issue3638 -- mount /mnt stgraber@castiana:~$ lxc stop issue3638 stgraber@castiana:~$ lxc start issue3638 stgraber@castiana:~$ lxc exec issue3638 -- mount | grep mnt stgraber@castiana:~$ lxc exec issue3638 -- systemctl -a | grep mnt mnt.mount loaded inactive dead start /mnt stgraber@castiana:~$ lxc exec issue3638 -- systemctl -a | grep sda dev-sda.device loaded inactive dead start dev-sda.device dev-sda.mount loaded active mounted /dev/sda stgraber@castiana:~$ lxc exec issue3638 -- ps aux | grep udev root 54 0.0 0.0 41720 1864 ?
