Ubiquity should support creating & install LTSP server

Registered by Dimitri John Ledkov on 2012-08-28

For the LTSP use case, another possible workaround for post-12.10 releases:
 * In the last stages of installation, copy the whole /target system to
/target/opt/ltsp/i386,
 * Chroot to /target/opt/ltsp/i386 and install ltsp-client and ldm,
 * Run /target/opt/ltsp/i386/usr/share/ltsp/cleanup to remove the user
account that was created, regenerate dbus machine id etc,
 * Install ltsp-server to /target,
 * And run /target/ltsp-update-image to generate a squashfs image in
/target/opt/ltsp/images/i386.img out of the fat chroot in
/target/opt/ltsp/i386.

This changes the default LTSP chroot to one that supports fat+thin
clients (instead of only thins), but with the current trends that
require 3d acceleration on desktops, that's probably a good thing.

And it only requires minimal network connectivity to generate the
chroot, or a couple of MB of packages in the installation media
(ltsp-server, ltsp-client, ldm).

.... apart from you want 64bit server & 32bit chroots for clients so this won't work for ubuntu desktop cd as pointed out by stgraber, but does work on edubuntu CDs.

Whiteboard

@stgraber: should this blueprint be moved to -edubuntu- namespace? You did demo some edubuntu/ubiquity work at the UDS...

Well, no, it shouldn't be moved to -edubuntu- because Edubuntu already has LTSP support in ubiquity where we ship an extra 400MB compressed i386 chroot on our DVD image and currently has no plan to change this implementation.
