	My favorite way to do this (has worked with Linux, *BSD, Mac,
	Win*, Solaris, Tru64, etc) is:

	dd if=/dev/cdrom of=cd-image.iso bs=1024

then
        dd if=cd-image.iso of/dev/cdrom bs=1024
just make sure you have room for that file
or choice I think sure work is
        dd if=/dev/cdrom of=/dev/burner bs=1024
just change burner to the real name of cd burner.

Yeah, someone at work just suggested that, too. Once you get past the
mental block of thinking you NEED to use mkisofs, this is the obvious
solution. :-)

	This also assumes that a cdrom is an iso9660 filesystem.

If you want to use mkisofs
1/ You need to mount the cdrom
2/ You need a bootable "file" ( dd of a bootable floppy )
3/ mkisofs -b bootfile -r -o /tmp/iso.iso

No, that's a sure-fire way to get a coaster.

	Get the CD-Burner-HOWTO and read how you capture the data from a
boot floppy to a file you read onto your cd-rom.
