Description Martin von Gagern 2011-09-25 00:07:18 UTC
For quite a while now, I've seen the following error message when booting my system:

 * Starting udevd                                             [ ok ]
 * Populating /dev with existing devices through uevents ...  [ ok ]
 * Waiting for uevents to be processed ...
udev[###]: failed to execute '/usr/sbin/alsactl' '/usr/sbin/alsactl restore 0': No such file or directory

udev[###]: failed to execute '/usr/sbin/alsactl' '/usr/sbin/alsactl restore 1': No such file or directory

 * Mounting /dev/pts ...                                      [ ok ]

The reason for the failure to execute that program is the fact that /usr isn't mounted yet at the time udev starts up; localmount is started a good while later on.

As the script /etc/init.d/alsasound should take care of saving and restoring mixer values for cold-plugged sound cards, I guess the best solution would changing /lib/udev/rules.d/90-alsa-restore.rules to only execute alsactl if the STARTUP variable is empty. Judging from the /etc/init.d/udev script, that should be a reasonable way to distinguish cold-plugging from hot-plugging.
Comment 1 Samuli Suominen (RETIRED) gentoo-dev 2011-09-25 07:08:05 UTC
Separate /usr is not supported without initramfs that mounts it before init.
Comment 2 Marcin Mirosław 2011-09-25 08:11:28 UTC
Does gentoo install guide mention separate /usr can broke some packages?

Proposed patch

This patch avoids the call to alsactl during startup. The alsasound init script will take care of those, if RESTORE_ON_START is set.

Where are you setting the STARTUP env var?

> Where are you setting the STARTUP env var?

The udev init script already does that.
Comment 6 Petr Zima 2011-10-28 14:17:22 UTC
Confirming, the same problem here. I am also using separate /usr and no initramfs.
Comment 7 Jan Hübner 2011-10-29 09:19:29 UTC
Why shouldn't that be supported? It worked all the time and is failing now.
Comment 8 Martin von Gagern 2012-01-04 11:23:52 UTC
Can someone please review my patch from comment #3, and either commit it or tell me what kind of problem he expects from it? Although this bug report here officially depends on bug #364235, the patch will work now even without a more general solution, and will still be required when there is a more general solution for /usr due to the fact that alsactl requires /var as well as /usr.
Comment 9 Marc Schiffbauer gentoo-dev 2012-01-05 13:52:45 UTC
I have the same problem here. Please apply the proposed patch.

Or use something like this maybe please:

Actually the /var issue has already been discussed with udev upstream, and their position is that this is a trivial failure we don't need to worry about since it will be picked up by init systems later.

For us, /etc/init.d/alsasound takes care of it.

Of course not initializing the alsa cards at that point is nothing to worry about. Whether it's due to missing /usr or missing /var doesn't matter at that point. Most people using a bootsplash won't even notice the message.

But there are enough people on this report here to conclude that some people at least are annoyed by those error messages, particularly as they refer to a non-problem. So let's simply not init cards there, and let the alsasound init script take care of things later on. In other words, apply my patch.

(In reply to comment #9)

Would work as well. But would silently ignore rare errors where alsactl isn't available. Also it would mean that people might see different behaviour depending on whether they have /usr in a separate partition or not. With my patch, you would get the same behaviour for all users. E.g. people who have disabled their alsasound init script will not get their cold-plugged cards initialized, no matter what partitioning scheme they use. Personally I'd consider this homogenity a feature.
Comment 14 William Hubbs gentoo-dev 2012-01-10 16:19:14 UTC
Since this is an issue with the alsa provided udev rules and not with udev
itself, there is really nothing the udev maintainers can do here.
I am re-assigning this to the alsa team.
