stage2 != ISO<br>
<br>
ISO is basically the stage1.<br>
stage1 is build by drakx-installer-images from:<br>
- some packages listed as BR, mainly the kernel drivers & firmwares<br>
- drakx-installer-binaries that provide the actual stage1 binary<br>
<br>
=> generates what is copied in isolinux/alt0 & in install/images/<br>
(*.img + *.iso)<br>
<br>
stage2 is build by drakx-installer-stage2<br>
<br>
=> generates what is in install/stage2: mdkinst.sqfs (a squashfs image)<br>
there's also rescue.sqfs there that is an alternate stage2 used when<br>
using the rescue.<br>
<br>
<br>
stage1 is basically a special initrd that loads the appropriate<br>
modules according to detected<br>
hardware and to what is specified on command line (eg: the DVD tells<br>
it to directly load<br>
stage2 from the DVD image).<br>
if not instructed to do sg, it displays the text menu asking from<br>
where to install (dvd, hard disk,<br>
network: http/ftp/nfs).<br>
It's a small statically linked program + init + a dhcp client +<br>
rescue-gui for the rescue menu<br>
<br>
it then loads stage2 (install/stage2/mdkinst.sqf or rescue.sqfs) from the URL<br>
<br>
stage2 is real system, with dynamic libraries, that starts:<br>
- an X11 server (if supported and if not asked for text mode)<br>
- udev<br>
and then go the install steps (language, license, partitionning,<br>
installing, summary, updates, ...)<br>
</blockquote></div><br>Hi Thierry,<br><br>I appreciate you taking time to reply and let me know these details. It confirms<br>my understanding. What I would like to know is how to create / master the DVD<br>installer ISO, and make that master contain a stage2 that I have built.<br>
<br>I have been able to build a stage1 boot.iso, but what I would like is build a<br>DVD image, based on Mageia-3-beta3-x86_64-DVD.iso, with just a different<br> stage2, and maybe a rebuilt stage1 if needed.<br><br>I guess someone must know how Mageia-3-beta3-x86_64-DVD.iso, and the<br>
other images get created. I don't want to rebuild all the packages that go in<br>them, just assemble one with the same packages as<br>Mageia-3-beta3-x86_64-DVD.iso, and a updated install/stage2/mdkinst.sqf file.<br><br>
Once this is figured out, I will happly update the Mageia wiki with details, which<br>I think will be helpful for anyone wanting to make customised Mageia DVDs.<br><br>Regards<br>Glen Ogilvie<br>
