Hey Seth,

I haven't heard anything in a long time.  But if this is going to pick
back up, can we come up with a detailed set of goals and requirements?
I don't recall whether the last version still worked like this, but I'm
still not comfortable with the idea of a system where after a reboot,
container-created root-owned files are owned by host root until a path
is specially marked.  Enforcing that the "source" directory is itself
uid-shifted would greatly ease my mind.
