Is there any way to tell lxc that I'll run it as root if I want root access,
and not to fiddle with capabilities? (If there's a ./configure option for
this, I haven't found it...)

One of the first containery bits that went into the vanilla kernel (in
2.6.15) was process-local mount points (I.E. shared subtrees):

But there's no mention of it on:
