Making the ISOs
The final step in this long process is getting the distro onto a CD for installation. First, we need to make ISOs from our discs, for which we use the mkisofs command. For the first disc, we'll use a few extra arguments to make the CD bootable.
For each subsequent CD, we can leave off the -b and -c arguments.
Finally, you'll need to implant the MD5 into the isos. Forgetting to do this could cause the ISOs to fail the media check, with an error saying "Unable to read the disc checksum from the primary volume descriptor".
To do this, we use the implantmd5sum command, which is part of the anaconda-runtime package:
To burn these ISOs, use the cdrecord command:
