It's actually both.
1) There is a a new installation mechanism involved (di-live) which we
wrote since Ubiquity doesn't (yet) run from the console in a live CD
type usage scenario.
2) There is a boot option ("install to hard disk") that will take you to
the installer first thing after the live system boots.
http://www.turnkeylinux.org/docs/screenshots
If you run the system "live", then di-live doesn't run by default but
you can invoke it manually (I.e., /usr/bin/di-live).
Our next batch of releases will include a curses configuration console
that will run by default and give you the option to invoke the installer
even if you boot into live mode, but its really just a matter of
providing a convenient user interface. Behind the scenes di-live, unlike
debian-installer (which runs in initramfs), always runs from a live
system.
di-live is mostly based on debian-installer with a bit of glue code
written in Python. You can find the source code here:
http://code.turnkeylinux.org/di-live/

Liraz

Somewhat along the lines of > what you are doing, I wrote: > > https://wiki.ubuntu.com/ServerFlavorSpec Bending DI and FAI to integrate complete systems is probably possible but the devil is really in the details and this seems to be quite a complex approach. From our experience the development process for pre-integrated purpose-specific systems can be quite complex as it is and (depending on your approach) may require a non-trivial investment in infrastructure (e.g., Canonical's infrastructure). Unfortunately, Canonical has enough on their plate without taking on the development of a whole family of Ubuntu-based appliances. If you have ideas for custom Ubuntu "flavors" (what we call appliances) you would like to see implemented in the near future, we would love for you to piggyback on our efforts and help nudge TurnKey Linux in the direction you are interested in! Experiment with Ubuntu, describe the appliance you would like to see built in enough detail (e.g., packages, configuration tweaks), we'll build it, sourceforge will host it, the community will test it, rinse, lather, repeat. The more people get involved the sooner we can have a whole bunch of opensource appliances to fill every nook and cranny. Cheers, Liraz |

Implementing this would require a bit of R&D work though. For example, how do you read all of the configuration settings from the Microsoft server and migrate them to Samba? I imagine you would need some software for that. Could this be made compatible enough with the old Microsoft server so that IT staff wouldn't have to run around reconfiguring anything or diagnosing various things that have suddenly broken? There is very little here that is special to a system running from a Live CD. The development approach that would probably work best is to set up a regular Ubuntu system in a VM on one hard drive, with Microsoft File and Print Server installed on another virtual hard drive. Then hammer the issues out until you get to the point where you the capability to read all the necessary configuration settings, and convert them into the equivalent Samba configuration settings. NTFS-3g driver could be used to access the original hard drives read/write so that you could re-use the existing filesystems and wouldn't have to migrate your data to a new partition. We have quite a bit on our plate right now as it is (with work and TurnKey), but if a community effort could get to the point where they can accomplish the transparent migration in a VM, and they publish the details, we will be delighted to do the extra work of turning that into a TurnKey Live CD appliance.

It seems to me that that would be the best way to get | community involvement. Thanks for the feedback! The development process for creating a Live CD from scratch is a bit complicated and that can raise the bar for involvement quite high. There is nothing secret about it though, it is pretty well documented: https://help.ubuntu.com/community/LiveCDCustomizationFromScratch And If you're looking for a more automated approach: http://www.gnewsense.org/Builder/HowToCreateYourOwnGNULinuxDistribution Most users will find it easier to get involved via testing, bug reporting, and participating in discussions on the forums and mailing list. We recognize that not everyone is a technical expert with a lot of free time on their hands and that besides development there are many other ways to make a valuable contribution to an opensource project, so that's what we're encouraging. BTW, hacking an existing appliance is much easier than building one from scratch and there are many tools available to help you do that that should be fully compatible with TurnKey Linux (e.g., UCK, remastersys). To lower the bar further, we'll also working on an easy customization mechanism: https://blueprints.launchpad.net/turnkeylinux/+spec/easy-customization Finally, we publish all of the source code to any custom components we create (e.g., di-live) here: http://code.turnkeylinux.org/ The binary packages themselves, which are fully compatible with Ubuntu hardy, are available at: http://archive.turnkeylinux.org/ I hope this helps.

Any package that isn't taken straight from Ubuntu's repositories can be found at our mini-repository at archive.turnkeylinux.org, and the corresponding source can be found at code.turnkeylinux.org. New packages have READMEs in them. For example: http://code.turnkeylinux.org/di-live/docs/README Modified packages, of which there are currently only three (casper, busybox-initramfs and turnkey-keyring) are also labeled in the package management system (e.g., casper is versioned 1.131-turnkey+15+g0374506). We had to modify casper because Ubuntu's casper hardwires various behaviors that don't need to happen in a server Live CD type scenario (e.g., X configuration) Ubuntu's developers did that because currently only Ubuntu runs the desktop versions (Ubuntu/Kubuntu/Xubuntu) "live". Ubuntu server can't run live and doesn't use casper, but TurnKey Linux appliances are mostly built for server tasks so we had to change that. The patches to busybox-initramfs change the built busybox configuration slightly to better serve TurnKey's different usage scenario (compared to Ubuntu). There are a couple of new packages in the appliances as well: we packages Joomla because nobody else would touch it due to frequent security issues and we wrote di-live as glue code that would allow debian-installer to run from a live CD usage scenario without a GUI (which Ubiquity needs). This kind of information is something I think might be good to add to the development wiki http://turnkey.wik.is/, maybe others are interested in it as well. If you have other ideas, we'd love to hear about them.
