[CentOS-devel] CD to DVD script

[Phil Schaffner]

The script below, a mod of

http://merlin.fit.vutbr.cz/mirrors/centos/build/mkdvdiso.sh

mentioned in

http://lists.centos.org/pipermail/centos-docs/2006-September/000039.html

works for me to create a DVD ISO from a set of C5 CD ISOs.  The
repo-tree part is still not working.  Any advice appreciated.

# A quick hack that will create a bootable DVD iso of a Red Hat Linux
# Distribution. Feed it either a directory containing the downloaded
# iso files of a distribution, or point it at a directory containing
# the "RedHat", "isolinux", and "images" directories.

# This version only works with "isolinux" based Red Hat Linux versions.

# Lots of disk space required to work, 3X the distribution size at
least.

# GPL version 2 applies. No warranties, yadda, yadda. Have fun.

#   Add optional 3rd parameter to specify location of temp directory
