You could make a 'template' of a full Slackware installation in btrfs
filesystem and then clone it each time you want a fresh LXC container.
The clone won't take any additional space on disk except for the changes
you make inside it.  After using it you can simply remove it and create
a new one for another build.

I have a helper script that simplifies the aforementioned steps.  You
can find it at <https://bitbucket.org/audriusk/lxc-slack>.  Haven't had
the chance to test it with updated btrfs-progs in -current, but it
should still work.
