Public bug reported:

When cloud-init shows a warning with Z99-cloudinit-warnings.sh (such as
on login after a ds-identify error), it suggests that you can:

Disable the warnings above by:
  touch /home/ubuntu/.cloud-warnings.skip
or
  touch /var/lib/cloud/instance/warnings/.skip

The second file (/var/lib/cloud/....) is not honored.

The easiest recreate is:
$ name="x1"
$ lxc launch ubuntu-daily:xenial $name
$ sleep 10
$ lxc exec $name -- sh -c 'd=/var/lib/cloud/instance/warnings/; mkdir -p $d; echo "WARNING WARNING FOO" > "$d/warn-foo"'

## see the warning is there.
$ lxc exec $name -- bash --login </dev/null
WARNING WARNING FOO

Disable the warnings above by:
  touch /root/.cloud-warnings.skip
or
  touch /var/lib/cloud/instance/warnings/.skip
mesg: ttyname failed: Inappropriate ioctl for device
  
$ lxc exec $name -- touch /var/lib/cloud/instance/warnings/.skip
## This time you should not see it, but you will.
$ lxc exec $name -- bash --login </dev/null
WARNING WARNING FOO
