[Solved] udev 174-1 issue

With the recent change to udev optical drives belong to disk group instead of optical. To play a dvd I either have to add my self to disk group or setup up a rule in /etc/udev/rules.d/ to change the group to optical. Those are the two methods that I've been able to make work but I believe they will be depreciated.

Moving forward how is archbang going to handle this? Policykit, udisks, what? If someone can shed some light on this for me I'd appreciate it.

Re: [Solved] udev 174-1 issue

Thanks for bringing this to attention!!

I'm not sure what's going to happen because apparently there will be more work done by Tom Gunderson this week on udev. Some things changed with storage as well. We'll have to wait to hear what Will says as he will be the one to make the decisions and changes.

Until then it is probably easier for everyone to:

  # gpasswd -a yourusername disk

to add yourself to disk group if watching DVD's is required for now.

For those of you who want to know what groups you are added to:

# nano /etc/groups

will show you the groups.

It think this is something that belongs in update warnings.
I will do it.

Re: [Solved] udev 174-1 issue

Also the other part of upgrade is udev isn't creating symlinks. So if needed you can add this to /etc/rc.local

# create optical drive symlinks
ln -s /dev/sr0 /dev/cdrom
ln -s /dev/sr0 /dev/cdrw
ln -s /dev/sr0 /dev/dvd
ln -s /dev/sr0 /dev/dvdrw

Below is an alternative method to adding yourself to the group disk. You can create your own udev rule in /etc/udev/rules.d
81-custom-optical-group.rules

# permissions for IDE CD devices
SUBSYSTEMS=="ide", KERNEL=="hd[a-z]", ATTR{removable}=="1", ATTRS{media}=="cdrom*", GROUP="optical"

# permissions for SCSI CD devices
SUBSYSTEMS=="scsi", KERNEL=="s[rg][0-9]*", ATTRS{type}=="5", GROUP="optical"
