[ale] ISO image from a mounted CDROM

[Cordell, Ron]

Thanks for the help - it was the mkisofs command that I couldn't
remember.

There's 2 choices really I've used.

While mounted run:
  mkisofs -J -R -V $1 -o Image.iso /mnt/cdrom

or unmount it and run the dd line below.  Neither one has any particular
advantages as the mounted CD wont creates a defragged or smaller image
than the original CD.  If you go the dd option below you can pass
different block sizes and make it faster if it's a very large CD but
that's probably not worth it on most modern CDROMs.
