to use the change_profile api when confined you need to explicitly list
the permissions in the profile

  change_profile -> <profile>,

where profile accepts an apparmor pattern matching expression

  change_profile -> /usr/bin/R//testprofile,

  change_profile -> **,


However there is a bug in change_profile in 11.04, and 11.10 that prevents
change_profile form working from a confined process (it works fine from
unconfined).  It has been fixed in 12.04 and we need to look at SRUing it
for previous releases.
