Description of problem: I have an IDE/ATAPI DVD drive on /dev/hdc and an IDE/ATAPI CD-RW drive on /dev/hdd. Red Hat Linux automatically configures the CD-RW drive as an IDE-SCSI device by adding hdd=ide-scsi to the kernel boot parameters. For consistency and improved performance, I have also configured my DVD drive as an IDE-SCSI device by adding hdc=ide-scsi to the kernel boot parameters. After rebooting, the SCSI devices in /dev are given the following permissions: brw------- 1 michael disk 11, 0 Jan 30 21:24 /dev/scd0 brw------- 1 michael disk 11, 1 Jan 30 21:24 /dev/scd1 crw-rw---- 1 root disk 21, 0 Jan 30 21:24 /dev/sg0 crw------- 1 michael disk 21, 1 Jan 30 21:24 /dev/sg1 To be able to consistently and completely use the DVD drive as a SCSI device (in particular to be able to rip music from an audio CD in the DVD drive using Grip), /dev/sg0 also needs to have permissions similar to /dev/sg1. Given the devices are owned by the user "michael", the user who is currently logged in to a local X session on the console via GDM, I am filing this bug under GDM, assuming it is what has modified the permissions on the SCSI devices, but has not also modified the permissions on /dev/sg0. Version-Release number of selected component (if applicable): gdm-2.4.1.3-2
It seems like this is handled by pam_console in /etc/security/console.perms. Changing component accordingly. pam-0.75-48
You need to read the man console.perms and change it accordingly to your modified configuration.
