I've seen clients where the @GMT comes next to the last path
component. That was part of the complexity of the previous
shadow_copy2 module.

To support the dumb clients the heuristic would have to be to try
inserting @GMT at all places where / now is if we lose the place the
client sent the @GMT initially. We can't rely on the flag being set I
believe. We're talking FreeBSD, (I believe AIX) and other custom SMB
clients that used to work.
