It's doable, but complicated by the fact that the container inits will
want to link /run/lock onto /var/locks, where /run is a tmpfs. But
you can just add
lxc.mount.entry = /var/locks var/locks none bind,create=dir 0 0
to make the host /var/locks show up in the container. Up to you do
then do the right thing with init :)
