Hello, the default shutdown policy for RBAC seems to fail under some configurations (namely debian wheezy).

By reading the kernel log it looks like the shutdown role is applied, somewhat, but is then dropped?

How did you shut the system down? Can you strace -f the command you used and mail me the log?

    Add /run/initctl to the shutdown role, protect /run by default in RBAC
    and automatically generate policies that protect it

Thanks for the report, and let me know if you continue to have any problems.

Thanks for the fix, works like charm!

p.s. I was a bit tired when I originally made the post but the system in question was actually running Debian testing (Wheezy). I fixed the original topic to better reflect reality

Brad,

I went to git clone gradm to build an updated package for Debian, but this latest commit doesn't seem to be in the cvsweb tree.

Many thanks.

It's there now, I hadn't pushed it out yet. I'll upload a new tarball tonight.
