Note you can also sign asynchronously from a tree compose.  For example,
your "integration" repository may be unsigned, and then later you
promote the tree after testing, and adding say a "gold" GPG signature.

The technology is mostly there for this, but the scripts are not.

This doesn't *have* to be done, but it means users have to manually
configure the mirror location when they start.  (This is the current
case with Fedora as we don't have mirroring sorted out).

Right.  Might as well ensure that the centos.org key is in
/usr/share/ostree/trusted.gpg.d so that when later the switch is made,
it's transparent to clients.
