[Apparmor-general] profile has no effect while using chroot to start application

Hi,

I'am using subdomain on a SLES9 SP3 with all relevant patches installed.
I can profile most of my application and it works as expected.

One of my colleague want's to run an application called expurgate in a
chroot environment.

I wrote a profile with an absolute path to the binary and no access to
any file.
Then I restart subdomain via rcsubdomain to reload the profile, and then
I execute the expurgate program with:
"exec env - /usr/bin/chroot /usr/local/eleven-2.0.6 bin/expurgate --configfile etc/... "

But I can't see any REJECT in the logfile.
Then I tried the path /**/bin/expurgate in the profile, but with the
same result.

I know it is more secure to run an application without chroot if I use a
subdomain profile, but my colleague wants to run the program in chroot
environment.

here is my profile (without glob):

--snip--
# vim:syntax=subdomain
# Last Modified: Wed Jul  4 14:13:12 2007
/usr/local/eleven-2.0.6/bin/expurgate {
  #include <abstractions/base>

  /usr/local/eleven-2.0.6/bin/expurgate mr,
}
--snip--

and here with glob:

--snip--
# vim:syntax=subdomain
# Last Modified: Wed Jul  4 14:13:12 2007
  /**/bin/expurgate {
  #include <abstractions/base>

  /**/bin/expurgate mr,
}
--snip--

Thank you for any help!
