Would that fix mean that the no-setuid, no-exec and other flags will 
work as well?

   I expect there will be things that need working on.  That's one of
   them.  Hmm.  We will probably have to hold the namecache entry for
   normal files and use the namecache's mount point to check for the
   read-only filesystem status.  No biggy (we already do this for    
directories to maintain the CD path), but it may take a few days to
   fix.
Talking of nullfs:  I'd strongly advise not to use it in its current 
state in production.  There are many things that need to be resolved 
first.  See my post on kernel@
