Thomas, I have a sinking suspicion that this is related to the new way you kill of daemons.

Jaideep, could you please give use the DAEMONS line from your rc.conf please?

I doubt that it is related, but I will look into it. Don't expect any answers soon, I have much work ahead of me.

I just had an idea. The problem could be related to this, so I need the DAEMONS list indeed: http://archlinux.org/pipermail/arch-dev-public/2007-October/002459.html

That's what I meant 8)
Sorry if I didn't explain it well enough, heh.

These are my daemons:

DAEMONS=(syslog-ng network iptables !netfs @crond @ntpd @cups dbus hal @alsa bluetooth avupdater avguard cpufreq slim)
Comment by Jaideep Das (jaideep_jdof) - Wednesday, 24 October 2007, 06:36 GMT
avupdater and avguard are the daemons for antvir antivirus for updating and on-access guard respectively.
Comment by Jaideep Das (jaideep_jdof) - Wednesday, 24 October 2007, 06:45 GMT
If i stop the avguard and avupdater daemon before shutdown, the shutdown process works fine.
Comment by Thomas Bächler (brain0) - Wednesday, 24 October 2007, 06:51 GMT
The avguard and avupdater don't seem to set add_daemon (which only touches a file with the same name in /var/run/daemons/). As those aren't official arch packages, you should add this:

In the beginning:
. /etc/rc.conf
. /etc/rc.d/functions

At daemon start:
add_daemon avguard (resp. avupdater)
At daemon shutdown:
rm_daemon avguard (resp. avupdater)

Closing this, as no official arch daemons script causes it.

Can you check to see if those scripts use the "add_daemon" script command? If not the scripts may need to be updated.

Thomas, any idea why it would hang? I was under the assumption this scripts would send sigterm, wait a bit, then send sigkill to everything remaining... is this not the case?

This problem wasn't there before the update. This means the problem is not with the daemons but with the shutdown script. And the solution provided isn't clear to me.

I agree here. While the daemons SHOULD be fixed, yes, I feel that we shouldn't assume all daemons will follow this all the time.

We have also not made a public announcement to the TUs or anything of the sort like this, so no one ever KNOWS to make these changes

Actually, we did: http://archlinux.org/pipermail/tur-users/2007-October/006050.html

Ah Touche!

Still, with something as variable as installable scripts like that that aren't always under our control, we should be more fault tolerant here.

Is this still an issue?
