Bug#677097: Two further information points

June 20th, 2012 - 03:40 am ET by Alan Chandler | Report spam
I have been pursuing the thought that udevd is trying to write to
/dev/.udev after its been moved to /run/udev, however I haven't found a
good testing regime. I have been trying to figure out how /dev/.udev
gets created (so it can be moved to /run/udev) but so far failed. The
only possible explanation I could find was in /sbin/MAKEDEV, but I don't
have that file on my system.

However a couple of possibly important pieces of information

1) If I start up in recovery mode, I still get all the "Failed to write
to queue file" messages, but I can log in with my usb keyboard. However
if I start up in normal mode, when I get to gdm the keyboard and mouse
are dead (but in X of course).

2) I experimented with with making udev depend upon $local_fs. It
didn't prevent the problem, nor did it help with locked keyboard and
mouse. However when I logged in to gnome3, it was effectively dead.
The mouse had no effect when moved into the top right corner. This
might have been co-incidence (I have noticed gnome3 susceptible to this
if I do it too quickly after startup) so I repeated it and the fault was
there the very next run. I then edited out the dependency in recovery
mode and restarted. Gnome3 started.

This happens in the initramfs. If /run doesn't exist, /dev/.udev is
used as a fallback. This should also occur if you don't use an
initramfs and /run is not available when udev starts.
