For me the dbus bug is stable since Otavio's patch which moved all chown stuff
from pkg_postinst to do_install [1]

In passwd/groups I have:
root@overo:~# cat /etc/passwd
...
avahi:x:999:999::/var/run/avahi-daemon:/bin/false
messagebus:x:998:997::/var/lib/dbus:/bin/false
root@overo:~# cat /etc/group
...
avahi:x:999:
netdev:x:998:
messagebus:x:997:
lock:x:996:
for messagebus group I see guid 997 and uuid 998 AND netdev uuid is 998!
After testing the patch - we are currently talking of - I have:
/var/run/dbus -> root:root
/var/lib/dbus -> 70:netdev
/usr/libexec/dbus-daemon-launch-helper -> root:netdev
and I swear before the patch I saw one of these files with owner avahi!
Is there some mechanism, enusring useradd/groupadd stuff working properly for
multiple threads adding users/groups at the same time?
