Comment 6 for bug 607636

Tested with Serge and confirmed to be a bug in LXC's Ubuntu template.

The generated "fstab" contains:
devpts /var/lib/lxc/drupal01/rootfs/dev/pts devpts defaults 0 0

Which shouldn't be present.
That line is causing /dev/pts on the "host" to be mounted with the wrong flags everytime one calls lxc-start on a container that has the above line in its fstab.

The workaround as mentioned before is to run: mount -o remount /dev/pts
and the temporary fix is to remove the line above from the container's fstab.

Here's a quick test I made to reproduce the issue:
root@castiana:~# grep pts /proc/mounts
none /dev/pts devpts rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000 0 0
root@castiana:~# lxc-start -n weblive01 -d
root@castiana:~# lxc-start -n drupal01 -d
root@castiana:~# grep pts /proc/mounts
none /dev/pts devpts rw,nosuid,noexec,relatime,mode=600,ptmxmode=000 0 0
