Re: cdrecord and devfs

[Martin Kuball <MartinKuball@web.de>]

Yes, I'm using ide-scsi for my CDRW drive. The necessary code is compiled 
into the kernel and I have the right boot parameter. And the drive shows up 
under /dev/scsi/... and not under /dev/discs/...

And to cite the cdrecord output again:
   scsidev: '/dev/scsi/host0/bus0/target0/lun0/cd:@'
   devname: '/dev/scsi/host0/bus0/target0/lun0/cd'
   scsibus: -2 target: -2 lun: -2
   cdrecord: Read-only file system. Cannot open 
   '/dev/scsi/host0/bus0/target0/lun0/cd' Cannot open SCSI driver.
   cdrecord: For possible targets try 'cdrecord -scanbus'. 

what file system it refering to? The devfs?
