[lxc-users] [ Fedora template ] Error while creating a new container

Couple of minor corrections and details...

Where ever I referred to release 1.1.0, I meant 1.1.2 in several places
below.

Also...  Rev 1.1.1 is currently in Fedora Rawhide but 1.0.7 is the
latest in Fedora 21 updates.

Regards,
Mike
