Thanks for the fast reply.
I also thought about this possibility but, I don't have a good feeling with 
Generally rsbac prohibits i.e. uid-changes as long as I do not allow them 
explicitly. Imagine what happens if the evil root-user manages to kill my 
setup-script. => Normally rsbac were up allowing nothing.OK But in the latter 
case rsbac runs softmode forever :((
The harddisk is mounted on /hdd.
My problem was that rsbac "forgets" its config (+AUTH_MAY_SUID) for a file (my 
400wrapper) on the harddisk. Doesn't it save everything for /hdd/... 
in /hdd/rsbac.dat (the one that survives reboot) or does it also save those 
things in /rsbac.dat (the one that doesn't)?
