# updateBuild.sh - Build the RedHat 7.3/8.0 CD installation images from 
# a distribution tree organized as on the redhat ftp site. 
# It executes the following operations:
# - Rebuild the hdlist and hdlist2 files in the RedHat/base directory
# - Rebuild the installer (useful if you have updated packages used 
#   during the installation phase) 
# - Split the main distribution tree into 5 trees whose size fits on a CD 
#   after a little reorganization of the tree (needed by splitdistro to work)
# - Regenerate the hdlist and hdlist2 files in the trees of the first 3 
#   CDs (the ones containing the RPMSs) 
# - Generate the 5 iso images to be burned on the CDs (the first one 
#   bootable)
#
# Environment variables (rhcd.conf): ANAPATH, RHVERSION, RHNAME, RHROOT, PKGFILE, 
#   DISTARCH, DISCR, ISODESTDIR, BOOTIMAGE, USEISOMD5
