[lxc-devel] snapshots location

[Serge Hallyn]

Hi,

Some time ago someone pointed out that the current lxc snapshot location
isn't ideal.  If you have a btrfs mounted at /var/lib/lxc, then the
snapshot locatoni /var/lib/lxcsnaps is not btrfs.

So I'm proposing that

1. we move the snapshot location to /var/lib/lxc/lxcsnaps
2. lxc_container_new() refuses 'lxcsnaps' as a container name
3. snapshot actions first check whether /var/lib/lxcsnaps exists; if so,
   and it is non-empty, then uses it.  Otherwise it uses the new
   location.

Any objections?  I didn't want to do this because I didn't want any
cruft under LXCPATH, but I think I'm ok with it, and I don't think
anyone should be bothering to ls /var/lib/lxc anymore, lxc-ls is so
much nicer.
