Bug Description


cloud-init status returns error, in groovy lxd containers.
This is probably happening because it expects /etc/fstab to exist, but it doesn't.

[Test Case]

$ lxc launch ubuntu-daily:groovy g
$ lxc exec g -- /bin/bash
root@g:~# cloud-init status
status: error

From /var/log/cloud-init.log :

This is also causing the autopkgtest failures in g, as the test 'docker-in-lxd' does:

+ lxc exec docker -- cloud-init status --wait
status: error

which fails the test.

This landed in, and I have since uploaded a new cloud-init package to groovy; it should migrate shortly.
