[Bug 925520] [NEW] lxc script non-root errors can be confusing

[Gary Poster]

Public bug reported:

A trivial thing, but at least a couple of people have been confused by
something like this, just being forgetful:

$ lxc-start -n lp
lxc-start: failed to cap_get_flag: Invalid argument
lxc-start: failed to create veth5HNAcN-vethyuiOEf : Operation not permitted
lxc-start: failed to create netdev
lxc-start: failed to create the network
lxc-start: failed to spawn 'lp'
lxc-start: No such file or directory - failed to remove cgroup '/sys/fs/cgroup/cpuset//lxc/lp'

The fix is to simply use sudo.  The error message does not communicate
this clearly.

I'd suggest that the lxc scripts that need to be run as root (is that
all of them except lxc-list?) have a "this script  must be run as root"
error message, or similar.  It's a small thing, but I think it would be
appreciated by users.
