First of all, if you replace an RPM, you'll need to do createrepro.
disc_info=`head -1 $BASE/$ARCH/.discinfo`
createrepo -v --baseurl="$disc_info" -g repodata/comps.xml $ARCH
If the RPM is a "system RPM", then you probably want to do a
buildinstall first to get it into the anaconda system (and get a new
disc_info),
a la:
$BASE/buildinstall --debug \
--version 5 --product 'CentOS' --release "CentOS 5" \
--prodpath CentOS $BASE/$ARCH 2>&1
If all you want is a mkisofs, what's wrong with the "man" command??
Maybe something like:
mkisofs -q -r -R -J -T -no-emul-boot -boot-load-size 4 -pad \
-b isolinux/isolinux.bin -c isolinux/boot.cat -boot-info-table \
-V "$VER ($date)" \
-A "$REL - $VER - $firmware" \
-publisher "$PUB" -p "$PUB" -x lost+found \
-o "CentOS-$VER-$date.iso" $ARCH 2>&1
... reboot, lather, rinse and repeat .... :-) :=)
You may find "re-generating" the CentOS CDs/DVD quite easy at
times and very frustrating and complex at others ......
