make .iso from bootable Redhat CD

[thedaver]

Instead of wanting to burn an .ISO, I want to MAKE an .ISO FROM a known good RedHat CD set I borrowed from my buddy. I'm particularly concerned about CD1 because it's bootable.

If it's enough to `cp -R` the whole enchilada from each CD and make an .ISO from there I guess I can manage, but I really hoped somebody had a truly slick way to solve this. OR AT LEAST some GOTCHAS to watch out for before I proceed.

Thanks,
D.

Try using 'dd'. It'll copy the CD byte-by-byte. Check out this quick run down:

To make an ISO from your CD/DVD, place the media in your drive but do not mount it. If it automounts, unmount it.

dd if=/dev/dvd of=dvd.iso  # for dvd
dd if=/dev/cdrom of=cd.iso # for cdrom
dd if=/dev/scd0 of=cd.iso  # if cdrom is scsi

To make an ISO from files on your hard drive, create a directory which holds the files you want. Then use the

mkisofs

command.

mkisofs -o /tmp/cd.iso /tmp/directory/

This results in a file called cd.iso in folder /tmp which contains all the files and directories in /tmp/directory/.

For more info, see the man pages for mkisofs, losetup, and dd, or see the CD-Writing-HOWTO at
