option 2 doesn't make sense.  using the cpu(1) as a test setup, please show how such a wstat would work atomically if one does 'mv /mnt/term/foo /tmp/foo'.  note that 'cpu' exports the local fs to the cpu it connects to (which is then mounted on /mnt/term). also one can 'cpu' to a different domain (i.e different fs).

How? Which 9p message would trigger the magic?

I just see 2 options:
1. Have a control file
2. Use custom wstat with full path to move

But if both are wrong, I'm lost.
