Just a wonder, about groups

[melodie]

Hi,

I just saw a list of messages from udevd in the boot messages of a newly installed PClos in one of my virtual machines. This say "udevd group scanner unknown".

I wonder if PClos would not need some more groups in it's system, basically ? Such as, scanner, and also such as optical : for all that concerns cdrom and dvdrom drives.

What do you think ? How is that handled in the distributions ? (From a developer's point of view)

I did this (in terminal as root)>
sudo groupadd scanner
to fix scanner unknown - before creating my kde4 remaster

sudo groupadd scanner to fix scanner unknown - before creating my kde4 remaster

Thanks Steve, I'll do the same before doing the next remaster. (Just next night I guess).

Else, what about the group assigned to /dev/cdrom ; /dev/cdrom0 ; /dev/dvd and so on ? I see in my Pclos installs they belong to root.root, whereas in Archlinux (and some other distros too I suppose) they belong to root.optical : which makes it practical I think, as my user login belongs to optical too !

(as well as audio, video, storage, scanner, camera and so on... )

Could someone explain me how the dvd and cdrom things (reading, burning... ) are managed in PCLinuxOS ? Aren't there sometimes problems with the access to thoses devices ? (Maybe now Policykit helps dealing with it ?)
