So I took a closer look and that isn't good enough. "rewrite"
requires either a session and a PIF or a PIF UUID. %post doesn't
have a session, and I don't see a way to easily get a PIF UUID.
"--force rewrite" does take a bridge name but it wants to
reconfigure that bridge, which %post doesn't want to do.
Can you suggest a way to do this then?
Thanks,
Ben.
