Indeed you may want reboot -n!

Hopefully not necessary for a read-only root.

Does it make a difference with just reboot (without -n) if the
filesystem is mounted read-only?

  What is the way around this problem?
 
 resize_ffs appeat to work like a charm from within the domU. I did it in
 single user with read-only root and just swap activated, and rebooted
 immediatly upon completion.

And make sure it does not have WAPBL on it.
