Hi Thierry,

I appreciate you taking time to reply and let me know these details. It
confirms
my understanding.  What I would like to know is how to create / master the
DVD
installer ISO, and make that  master contain a stage2 that I have built.

I have been able to build a stage1 boot.iso, but what I would like is build
a
DVD image, based on Mageia-3-beta3-x86_64-DVD.iso, with just a different
 stage2, and maybe a rebuilt stage1 if needed.

I guess someone must know how Mageia-3-beta3-x86_64-DVD.iso, and the
other images get created.  I don't want to rebuild all the packages that go
in
them, just assemble one with the same packages as
Mageia-3-beta3-x86_64-DVD.iso, and a updated install/stage2/mdkinst.sqf
file.

Once this is figured out, I will happly update the Mageia wiki with
details, which
I think will be helpful for anyone wanting to make customised Mageia DVDs.

Regards
Glen Ogilvie
