After finishing the k3bsetup and starting it for the first time it tells me that it can't find cdrecord and cdrdao. I checked the config and everything was fine. Then i opened the console and made "which cdrecord" with no result. I logged in as root and it told me that cdrecord is in /usr/bin/cdrecord. Permissions were "-rws--x---". A "chmod o+rx /usr/bin/cdrecord /usr/bin/cdrdao" fixed the mess... But I used xdroast (enabled user mode and worked as user) before. And Yes! I'm in the cdrecording group! mfg Nomike aka Michael Potmann
Seemes that the Problem is a conflict between k3b and xcdroast. xcdroast needs to set special permissions to work in "non-root" Mode. But with this Settings k3b doesn't work. And xcdroast doesn't work with the Settings k3b is needing.
Both xcdroast and k3b would work in a non-root-mode with the setuid-bit set on cdrecord. But I'm feeling a bit uncomfortable to change the ebuilds, so that this tools will be installed with setuid set. I think, that is a question for the user. Both GUI applications print a nice message after start, so the user knows, what he has to do. I will change this bug to WONTFIX, but you could still give arguments, on what I should change ;-)
