[gentoo-user] udev issue? (No /dev/cdroms/XXX on two machines)

[gentoo-user] udev issue? (No /dev/cdroms/XXX on two machines)

[Mark Knecht]

Hi,
   It seems that on two of my machines, after recent updates, I no
longer have /dev/cdroms and therefore cannot mount CDs, etc. I can
mount them by hand using the old style /dev/hda. The hardware works.
It just seems that udev is now doing something different.

   Has anyone else seen this of late?

   I am set up as "auto" for the udev/devfs choice in /etc/conf.d/rc,
as well as not using a tarball. udev is up and running:

gigastudio ~ # ps aux | grep udev
root       854  0.0  0.0   1468   484 ?        S<s  10:30   0:00 udevd
gigastudio ~ #

gigastudio ~ # emerge -pv udev

These are the packages that I would merge, in order:

Calculating dependencies ...done!
[ebuild     U ] sys-fs/udev-068-r1 [068] (-selinux) -static 0 kB

Total size of downloads: 0 kB
gigastudio ~ #

   Any ideas why this might happen and where I'd look to solve the problem?

   All machines have been rebooted, etc.

Thanks,
Mark

I saw this too, with udev-070. I tried everything I could to rule out it
being udev, but I was unable to do so. I filed a bug, it would help if
you could provide your details there.

Done.

In my case the drives are there and working, but the /dev/ names are
more old style.

mark@lightning ~ $ ls /dev/cdr
cdrom   cdrom1  cdrw    cdrw1
mark@lightning ~ $ ls /dev/cdrom
/dev/cdrom
mark@lightning ~ $ ls -al /dev/cdrom
lrwxrwxrwx  1 root root 3 Sep 27 00:52 /dev/cdrom -> hda
mark@lightning ~ $ ls -al /dev/cdrom1
lrwxrwxrwx  1 root root 3 Sep 27 00:52 /dev/cdrom1 -> hdb
mark@lightning ~ $ ls -al /dev/cdrw
lrwxrwxrwx  1 root root 3 Sep 27 00:52 /dev/cdrw -> hda
mark@lightning ~ $ ls -al /dev/cdrw1
lrwxrwxrwx  1 root root 3 Sep 27 00:52 /dev/cdrw1 -> hdb
mark@lightning ~ $

Everything is working except I'd have to change fstab to make it easy.
Thought I'd ask if there was a known change about udev naming that I
hadn't heard about.

Thanks,
Mark

I am pretty sure this is intentional.  The /dev/cdroms/XXX syntax was 
"devfs" style, which is now dead.

See the devel list thread starting at:
http://thread.gmane.org/gmane.linux.gentoo.devel/29504

Or the udev change log at:
http://www.gentoo.org/cgi-bin/viewcvs.cgi/*checkout*/sys-fs/udev/ChangeLog

Thanks for finding this Richard. It does look like it's an intentional
change. I guess it's time to start editing my fstab files.

Cheers,
Mark
