Cdrecord has not been tested on OpenBSD jet. 
It should run anyhow because the differences between the *BSD 
systems should not be that big.

As *BSD does not have the standard UNIX functions ecvt() fvct() and gcvt()
printing of ploating point numbers has been disabled. However
the floatingpoint arguments are skiped so the programs will not dump core.
This problem currently only applies to the verbose output of mkisofs.

The current *BSD port will not yet be able to access
the CD-Recorder as it is on other architectures.

User level SCSI seems not be be well tested on *BSD

It would be nice if the kernel hackers of all *BSD flavors could aggree in
adding decent and useful SCSI user land transport support.
This would cause the following canges:

	-	Add a driver that is present by default and offeres an
		easy to address interface to the /dev/ namespace.
	-	Create device file entries for this driver by default.
	-	allow to send all commands on this driver even if the main
		driver entry is in use, At least allow:
			INQUIRY
			TEST_UNIT_READY
			REQUEST_SENSE
		to be able to scan the SCSI bus for drives.

Workaround:

If /dev/su0-0-0 ... does not exist on your systen, you may try
to create the devices with the MAKEDEV.su script below.
You may try to symlink /dev/scgx to the real driver entry for your device.
If e.g. the CD-Recorder is on /dev/cd0a, you can do:

cd /dev
ln -s cd0a scgx

or

cd /dev
ln -s cd0c scgx

or

cd /dev
ln -s cd0.ctl scgx

You then will be able to access the CD-Recorder as on other
systems. If your CD-Recorder is on SCSI Bus 0, Target 2, lun 0
type:

cdrecord dev=0,2,0 .....

I hope to get cdrecord work better with your help soon.
