Bug Description
Because devtmpfs is now mounted in containers, and /dev/shm is a symlink in devtmpfs, lucid containers now fail to start.
=======
SRU Justification:
1. Impact: newly created lucid containers cannot be started, and changes in
the container's /dev are seen in the host's /dev.
2. Development fix: devtmpfs is removed from the container fstabs
3. Stable fix: same as development fix
4. Test case:
1. sudo lxc-create -t ubuntu -n l1 -- -F -r lucid
2. sudo lxc-start -n l1 -d
3. sudo lxc-ps -n l1
Only three tasks will show up in lxc-ps, because lxc-start will hang at
mountall when failing to mount /dev onto a symbolic link (/dev/shm).
5. Regression potential: This will require workarounds in the cloud images
(which recently stopped including a populated /dev, and will need to do so
again). That will be fixed by utlemming by Oct 25. It also regresses a bug
in grub updates in containers. This will need to be worked around by having
update-grub detect that it is in a container, and not fail due to non-existing
/dev/root in that case.
