I do 'emerge cdrtools' and cdrecord works fine, both as a normal user (obviously with priority 0) and as root. I launch k3bsetup, leaving the option "use cdrecord group" unchecked, and it becomes completely impossible for normal users to burn CDs (it will still work for root), both using k3b and cdrecord: $ cdrecord -v -dao -eject speed=32 fs=32 dev=ATAPI:0,0,0 driveropts=burnfree DataCD1.iso cdrecord: Fifo size 32 too small, turning fifo off.

Obviously, this way you'll get priority 0 when running as a normal user, which is bad.
