apparmor/utils/unconfined
John Johansen 77caea2cc7 'unconfined' can appear to mix up process names eg. (/usr/bin/rsync vs.
/usr/bin/rsyncd) bnc#408869

The unconfined tool shows:

[...]
29799 /usr/bin/rsync not confined
29799 /usr/bin/rsync not confined

This is because unconfined is grabbing the post symlink resolved exe filename
which for /usr/sbin/rsyncd is /usr/bin/rsync.

To fix this provide both the cmdline and exec name in parenthesis when the
exe name and the cmdline name differ.

For the above example you would see
29799 /usr/bin/rsync (/usr/sbin/rsyncd) not confined
