Details

The latest udev package breaks many things:
- sound doesn't get registered anymore
- v4l devices don't get registered anymore
- printers don't get listed in /dev/lp/ anymore

Besides these, I think some other things might be broken too.
This task depends upon

Hmm, I don't have a printer or a v4l device on this machine. But my snd/ and sound/ devices are fine.

Can you elaborate or tell me how to reproduce?

Here are the new rules added by tpowa. I don't see anything that would affect those devices.

I get a "/dev/pts busy or already mounted" message during "mounting filesystems" stage of bootup with udev 0.50-2.

That's harmless, i'll have it out of there by 050-3.

I've modified start_udev to try to umount pts and shm before it rebuilds all the device nodes, then re-mount them afterwards. This should save the additional step required when running start_udev manually:

# /etc/start_udev
# mount /dev/pts
# mount /dev/shm

After downgrading to 0.50-1 and killing udevd and starting /sbin/udevstart, all devices registered correctly. Could it be something with the bootup scripts that doesn't work? The problem happened after rebooting, which hadn't been done after upgrading to 0.50-1, so the problem could be in that release too.

The problem persisted after every reboot with 0.50-2, haven't had time to check if 0.50-1 has the problem too.

050-3 is going up now. Please check if that one breaks as well.

I just upgraded to .50-3, seems to solve my problem.
