How to Burn CDs Under Linux                08/23/2004

I wanted to burn the images/boot.iso image from the first RHEL CD so I
could use it to install.

Basically, one uses cdrecord to burn an image.

First, determine the address of your CD writer.
   cdrecord -scanbus

On jenny, this returned

The Plextor CD/RW is address "1,2,0", so my cdrecord command will be
   cdrecord -eject -dummy dev=1,2,0 -v /mnt/cdrom/images/boot.iso
to do a test (i.e. "dummy") run,

or cdrecord -eject dev=1,2,0 -v /mnt/cdrom/images/boot.iso
to really write it.

To burn a whole directory tree to a CD, you first must create a CD image file
from that directory, then you can feed that CD image file to the cdrecord
command.

To create an image for a ISO 9660 filesystem with Rock Ridge extensions,
  mkisofs -R -o cdimage.raw /master/tree
then you would
  cdrecord -eject dev=1,2,0 cdimage.raw
And of course, you can combine these two steps into one with pipe,
like what we did to write Sandy's data on jenny,
  mkisofs -R weekly_backups/pct | cdrecord -eject dev=1,2,0 -
But this was 3.5GB, so wouldn't fit on a simple CD.  It failed with

This worked, though
  mkisofs -R weekly_backups/pct/SPIDI_042005.tar.gz | cdrecord -eject dev=1,2,0 -
since that one file was only 591MB.
