[lxc-devel] RFC: aliases

[Serge Hallyn]

Hi,

one idea that has been brought up is to support 'aliases'.  So if you're
locally building a daily pristine container, say at 'c-2013-08-20',
you might want to then have a 'c-latest' alias or link pointing to the
latest container, so you can always just

	sudo lxc-clone -o c-latest -n test1 -s

The most obvious idea would be to use a symbolic link.  However, while
that mostly works, it's actually not perfect - lxc_container_new()
will be called with the name you passed in (c-latest), not with the
symlinked name.

Another idea would be to support a $lxcpath/$lxcname/config consisting
of only 'lxc.alias = c-2013-0820'.

Do people have any other ideas?

I'm thinking symbolic link may be the simplest thing to support -
lxc_container_new() could immediately readlink() to get the real
container name.
