[As I recently wrote on the "newbie" and "cooker" lists . . .]
Yes, the CD-RW issue is quickly becoming a FAQ on the expert list
(thanks for at least picking the other two lists instead!)
Mankrake 7.0 has a bug (evidently not fixed in in 7.0v2) whereby for a
CD-RW it correctly sets up the LILO parameters to tell it to use
ide-scsi emulation (necessary for CD-RWs under Linux) but fails to make
the corresponding change to the /dev/cdrom links.
Just
rm /dev/cdrom
ln -s /dev/scd0 /dev/cdrom
