In the puias.py file, additional yum groups defined.  puias.py in product.img, product.img is loaded by loader from anaconda runtime.
 yum groups

 * pu
 * ias
 * computational

suggest alternative package groups like pu-free pu-nonfree etc.

drop optional.

= DVD =
{{{
/usr/libexec/anaconda/makestamp.py used to make a .discinfo file.
/usr/libexec/anaconda/mk-images used to make .treeinfo file.
}}}

Rsync the tree then remove things not needed on the dvd
{{{
[thomas@host puias]$ rm mirrorlist
[thomas@host puias]$ rm Computational
[thomas@host puias]$ rm repodata.outside
[thomas@host puias]$ rm PUIAS/repodata.outside
[thomas@host puias]$ rm -r PUIAS/repoview
}}}

See redundant.

{{{
[thomas@host puias]$ rm images/puias-6.1-x86_64-DVD*iso
}}}

Make directories for the discs and move Addons to the 3rd disc.
{{{
[thomas@host puias]$ mkdir 1 2 3
[thomas@host puias]$ mv Addons 3
[thomas@host puias]$ mv EFI EULA GPL images isolinux mirrorlist Packages PUIAS repodata RPM-GPG-KEY-puias 1
[thomas@host puias]$ mkdir 2/Packages
[thomas@host puias]$ cd 1/Packages
}}}

Move large packages over to second disc, trying to make disc 1 small enough for a DVD. 
Move things that usually aren't required for a server build

{{{
[thomas@host Packages]$ mv *-devel-* ../../2/Packages/
[thomas@host Packages]$ mv eclipse-* ../../2/Packages/
[thomas@host Packages]$ mv texlive-* ../../2/Packages/
[thomas@host Packages]$ mv openoffice.org-* ../../2/Packages/
}}}

Go back up to the root.
{{{
[thomas@host Packages]$ cd ../../
}}}

Remove the repodata in the root and then move the one from PUIAS to the root

{{{
[thomas@host puias]$ rm 1/repodata
[thomas@host puias]$ mv 1/PUIAS/repodata 1
[thomas@host puias]$ ln -s ../repodata 1/PUIAS/repodata
}}}

Start a createrepo with a split and media (cd path)
{{{
[thomas@host puias]$ createrepo -v -g repodata/comps-puias6.xml --split 1 2 -u 'media://1306249229.307081'
}}}

Create a .discinfo and .treeinfo the numbers need to match here
.discinfo
{{{
--- BEGIN ---
1306249229.307081
PUIAS Linux 6.1
x86_64
1



--- END ---
}}}

.treeinfo
{{{
--- BEGIN ---
[general]
family = PUIAS Linux
timestamp = 1321026136.00
variant = PUIAS
totaldiscs = 1
version = 6.1
discnum = 1
packagedir = 
arch = x86_64

[images-x86_64]
kernel = images/pxeboot/vmlinuz
initrd = images/pxeboot/initrd.img
boot.iso = images/boot.iso

[images-xen]
kernel = images/pxeboot/vmlinuz
initrd = images/pxeboot/initrd.img

[stage2]
mainimage = images/install.img
--- END ---
}}}

If you have time, make some checksums for a few things:
from yum.misc import checksum
checksum('sha256','images/pxeboot/vmlinuz')
then put that in the checksums section of .treeinfo
{{{
--- BEGIN ---
[checksums]
images/pxeboot/initrd.img = sha256:7dd1303afa583c00cba591d4c397f31df08f05c15f4947eb2143cbb7a0b32811

--- END ---
}}}

Now remove all anaconda repo files.
{{{
[root@host puias]# cd images
[root@host images]# mkdir /mnt/install
[root@host images]# mount -o loop install.img /mnt/install
}}}

(requires squashfs stuff installed)

{{{
[root@host images]# cd /tmp; cp -a /mnt/install install
[root@host /tmp]# cd install
[root@host install]# rm etc/anaconda.repos.d/*
[root@host install]# mksquashfs * ../install.img:w
[root@host install]# cp /tmp/install.img ~/puias/1/images/

}}}
Now make an iso out of those directories...

{{{
[root@host puias]# cd 1
[root@host 1]# mkisofs -o /tmp/6.1-DVD-x86_64.iso -r -b isolinux/isolinux.bin -c isolinux/boot.msg -cache-inodes -no-emul-boot -boot-load-size 4 -boot-info-table -R -m TRANS.TBL .
[root@host 1]# cd ../2
[root@host 2]# mkisofs -o /tmp/6.1--DVD-2-x86_64.iso -r -cache-inodes -R -m TRANS.TBL .
}}}


=== Note: ===
There is a bug in createrepo that causes it to rewrite all the files incorrectly in primary.xml
There is a string replace that is unended, replaces all occurences of _reldir with '', which replaces 1 and 2 with nothing

relpath = self.localpath.replace(self._reldir, '')
change the line to this:
relpath = self.localpath.replace(self._reldir, '',1)
