It's quite easy to create one.  In fact, you might notice that discs 2-4
of ES and AS 3 have the same MD5 checksums, which means you only need
disc one of ES/AS and can use the rest from either.

  I have a single DVD with redhat-release*.rpm in /EXTRAS so I can do
rpm -Uvh --force after installing to set it to the appropriate release.
I _think_ this is the only major difference between disc 1 of AS/ES,
since I haven't found any problems yet.  The redhat-release rpm swap
works nice with kickstart, too, since you only have to keep one copy of
the binaries around and can install the proper redhat-release in the
%post script.

I think it's something like:
for i in /somewhere/*.iso
do
	mount -o loop $i /mnt/cdrom
	find /mnt/cdrom |cpio -pvdmu /somewhere_else
	umount /mnt/cdrom
done
cd /somewhere_else/mnt/cdrom

      -R -J -m TRANS.TBL .
dvdrecord --eject -v dev=0,0,0 redhat-dvd.iso

Of course, this requires a bunch of disk space.  A lot of the above
procedure is derived from http://www.securecode.net/displayarticle7.html
which requires a little less disk space.
