No idea if there is a howto, but my SCSI 'Toshiba SD-W1101 DVD-RAM'
drive entry (I didn't add it - install or kudzu did) in fstab is:
/dev/cdrom  /mnt/cdrom  udf,iso9660 noauto,owner,kudzu,rw 0 0
/dev/cdrom is /dev/scd0

And my IDE 'Ricoh CD-R/RW MP7040A' is:
/dev/cdrom1  /mnt/cdrom1  udf,iso9660 noauto,owner,kudzu,ro 0 0
/dev/cdrom1 is /dev/scd1 (and ide-scsi is on)

OK - now I'm interested - lets see if I can format a CDRW disc
as UDF on my CDRW drive...

1) to get the scsi device number: 'cdrecord -scanbus'
   gives: DVD-RAM = 0,2,0 and CDRW = 1,0,0

2) I have a CDRW disc with audio on it ... can check with:
   'cdrecord -dev 1,0,0 -toc'

3) In /etc/fstab I guess the CDRW 'ro' should be 'rw' like for
   the DVD-RAM drive (everything else is the same!)

4) Search the RH packages for anything with 'udf' in it - nope :-(
   Only interesting thing I found was docs saying rw doesn't work?
   Then how come it does for me?
   I'm using 2.4.20-13.9

5) Search the net ...

I found udf-utils from sourceforge and it compiled fine and
installed, but I couldn't get it to work - the linux kernel
is 0.9.5 of UDF but I doubt that's a problem

The command 'pktsetup /dev/pktcdvd0 /dev/cdrom1' fails.

Looks like I jumped the gun here - oh well.

Anyone who actually knows what they are doing (unlike me)
- know how to get it to work?
