[Bug 1271000] Re: lxc-start fails with Out of memory reading cgroups

Ok, thanks.

For anyone reading this report who may not be clear on it, the current
behavior is: a template exists to fill in a rootfs.  If no template
is specified, then it is assumed that a rootfs has already been created,
and only the basic metadata (rootfs location etc) are to be filled in.
People do rely on this behavior.  So the question is how to best avoid
the (more common imo) case where a user accidentally does not specify a
template.  We could force the existing no-template users to switch to
specifying '-t none'.  We could simply document the current behavior.
We could print out a warning about there being no template, but not
change the default behavior.  Not sure if there are any other ideas.

So the question is how to best handle this without causing trouble
for people who rely on this default behavior.
