# ks-server.php  - Dale Bewley <dale a/t bewley.net>
#-------------------------------------------------------------------------------
# This PHP should be called from a kickstart config file in the %post section.
# The output of this script will be a shell script which is customized based
# on the arguments passed in by kickstart.
#
# Kickstart won't let you use '?' in a %ksappend URL apparently, so you can't
# use query_string and must use path_info instead. However, I've abandoned the
# %ksappend macro anyway. I know call this script like this:
#
#	wget -O /root/ks-post-config.sh \
#		"http://ks/ks-server.php?mac=${MAC_ADDR}&dist=${DIST}"
#	chmod 700 /root/ks-post-config.sh
#	/root/ks-post-config.sh
#
# This script assumes a directory structure something like this:
#
#	[root@noc ks]# find scripts
#	scripts
#	scripts/fc4
#	scripts/fc4/ks-fc4-mac-00-09-3D-10-FF-FF.sh
#	scripts/fc4/ks-fc4-yum-config.sh
#	scripts/fc4/ks-fc4-mac-00-09-3D-11-FF-FF.sh
#	scripts/fc4/ks-fc4-buildhost.sh
#	scripts/fc4/ks-fc4-yum-rt.sh
#	scripts/fc4/ks-fc4-mac-00-09-3D-12-FF-FF.sh
#	scripts/fc4/ks-fc4-scsi-fix.sh
#	scripts/fc4/ks-fc4-yum-update.sh
#	scripts/fc4/ks-fc4-ntp-config.sh
