I have at present two emulated SCSI devices on my system; a USB flash
drive, and a DVD-writer.
They get assigned:
0,0,0 0) 'SanDisk ' 'Cruzer Micro ' '2033' Removable Disk
2,0,0 200) 'HL-DT-ST' 'DVDRAM GSA-4160B' 'A300' Removable CD-ROM
if the USB device is present at boot time (I think).
So my script for burning CDs, which says:
mkisofs -J -L -R -o x1.iso "$*"
cdrecord -v dev=2,0,0 x1.iso
rm -f x1.iso
is very fragile.
How should I do it? Write a script to read the output of cdrecord
-scanbus and grab the device number? There has to be a "right" way, and
instinct says this isn't it.
