[Bug 1379030] [NEW] Extra lxc.mount.auto entry being added to config file

[Christopher Townsend]

Public bug reported:

I'm using the Python API to append entries to the LXC config file.  When
I do the following:

container.set_config_item("lxc.mount.auto", "cgroup:mixed")

I get an extra lxc.mount.auto entry in the config file.  This is what it
looks like:

lxc.mount.auto = 
lxc.mount.auto = cgroup:mixed

This keeps the container from starting.  I have to remove the first
lxc.mount.auto to get the container to start.

Also, this seems to have started fairly recently.
