Re: K3B CD-burning Dell 700m laptop, Only burns while root
It won't. That is what I meant by the 2.6.8+. Linux and other
developers closed off some scsi commands so that only root can use
them. It was done for security so that people can not write over a SCSI
HD like it was a cd. cdrecord's developer is supposed to use SUID to
correctly access those commands. To my knowledge that has not been
completed. Until it is, you will have to burn cds as root or create a
wrapper script using sudo. An example script is below.

#!/bin/sh
