I am running Slackware 10, upgraded to current, with a 2.6.8.1 kernel. I
am having some trouble with udev permissions.

I have a dvd-rom (/dev/hdd) and a dvd-rw (/dev/hdc). I also have
/dev/cdrom and /dev/dvd, both of which are symlinks to /dev/hdd. All of
these (/dev/hdc, /dev/hdd, /dev/cdrom, and /dev/dvd) are root:cdrom 660.

I want to make a /dev/dvdrw which is a symlink to /dev/hdc. What I did is
rename /etc/udev/rules.d/udev.rules to /etc/udev/rules.d/50-udev.rules and
created a file (/etc/udev/rules.d/10-local.rules with the following line:

BUS="ide", KERNEL="hdc", NAME="%k", SYMLINK="dvdrw"

I rebooted to see if it worked, and the answer is.... sort of. I now have
/dev/hdc root:disk 660, /dev/hdd root:cdrom 660, /dev/cdrom (symlink to
/dev/hdd), /dev/dvd (symlink to /dev/hdd, and /dev/dvdrw (symlink to
/dev/hdc). What I want is for /dev/hdc to be root:cdrom.

I have tried several solutions, but none of them have worked for me. The
first was to edit /etc/udev/permissions.d/udev.permissions. Changed the
following section:

# optical devices
sr*:root:cdrom:660
scd*:root:cdrom:660
pcd*:root:cdrom:0660
cdrom*:root:cdrom:0660
dvd:root:cdrom:0660
rdvd:root:cdrom:0660
cdroms/*:root:cdrom:0660

My first sttempt, I changed it to look like this:

# optical devices
sr*:root:cdrom:660
scd*:root:cdrom:660
pcd*:root:cdrom:0660
cdrom*:root:cdrom:0660
dvd*:root:cdrom:0660
rdvd:root:cdrom:0660
cdroms/*:root:cdrom:0660

No dice. So I tried this:

# optical devices
sr*:root:cdrom:660
scd*:root:cdrom:660
pcd*:root:cdrom:0660
cdrom*:root:cdrom:0660
dvd:root:cdrom:0660
dvdrw:root:cdrom:0660
rdvd:root:cdrom:0660
cdroms/*:root:cdrom:0660

Still no luck. Does anyone have any ideas? I would like to be able to do
this without using chgrp in /etc/rc.d/rc.local.

Thanks in advance,

Shilo
