Description of problem:
Here is what happens when I hotplug my external DVD writer. Note that
PAM needs to be updated; I've manually had to add the /dev/sr* entry.

[root@laptop ~]# cat /etc/security/console.perms|grep /dev/sr
<cdrom>=/dev/cdrom* /dev/cdroms/* /dev/cdwriter* /mnt/cdrom* /dev/sr*
[root@laptop ~]# ls -l /dev/sr0
ls: /dev/sr0: No such file or directory

[root@laptop ~]# #insert device

[root@laptop ~]# ls -l /dev/sr0
brw-------  1 root root 11, 0 Aug 17 01:02 /dev/sr0
[root@laptop ~]# /sbin/pam_console_setowner /dev/sr0
[root@laptop ~]# ls -l /dev/sr0
brw-------  1 root root 11, 0 Aug 17 01:02 /dev/sr0
[root@laptop ~]# /sbin/pam_console_apply
[root@laptop ~]# ls -l /dev/sr0
brw-------  1 david root 11, 0 Aug 17 01:02 /dev/sr0

Do you have selinux enabled??
Comment 2 David Zeuthen 2004-08-20 04:49:44 EDT

[root@laptop ~]# selinuxenabled
[root@laptop ~]# echo $?
Comment 3 David Zeuthen 2004-08-20 04:54:48 EDT
Btw, there is a related bug, bug #130095, that suggest that udev
should create symlinks such that console.perms will work without
changes when the console changes owner.

Beware, you can't open(2) the device file (that's bug #130232 which is
closed as WONTFIX) so you need to look at /proc/ide/hd?/media or

Comment 4 Harald Hoyer 2004-08-20 05:46:37 EDT
ok, found the bug... the console.lock file changed its location.
Comment 5 David Zeuthen 2004-08-20 05:48:50 EDT
Great, should I file a new bug regarding the symlinks?
