Permissions

At times you might find that root can blank and burn CDs but not a user. You may get the message:

cdrecord: Operation not permitted. Cannot send SCSI cmd via ioctl
This might be because cdrecord has not been installed with the setuid flag set, and thus the user does not have enough permissions. Fix this with:
$ sudo chmod +s /usr/bin/cdrecord.mmap
or
$ wajig reconfigure cdrecord
