Doesn't look like that's made it in.  Don't remember noticing that patch
before (sorry, Andre), but it looks like a worthwhile feature, +1 from me.

Assuming you mean to replace the $rootfs in the mount target spot,
don't!  Just use the relative pathname.  I.e.

lxc.mount.entry = proc    proc   proc    nodev,noexec,nosuid 0 0
lxc.mount.entry = /shared shared none    bind 0 0
