You could really do with describing what you want, how much autonomy etc. You could also do with not using colors and italics in your posts.

Hi there,

I may be wrong, but from my knowledge I'd say that isn't possible. Well, of course you can start the setup on all machines in parallel, but they would still work themselves through the setup independently. That's not what you want, I assume.

Guess you misunderstood that.
What you can do is set all your machines to boot from network, and have all the necessary files on a PXE boot server. Then all client machines load their OS directly from the server when they boot, and none of them would need an actual OS installation of its own (they don't even need their own hard disks).
I don't know, however, how to do it exactly; I just know the technique as such. And I wouldn't like to have it that way, because it contradicts my principle: Every PC must be able to run self-contained; network may enhance operation, but it must not be vitally necessary.

Looks to me that you're reading too much into not-that-great English. May be wrong...

Hi there,

huh? Could you be more specific?
It's okay to criticize, but rather than just being cryptic, please do it in a way I can profit from.

It is possible to install any linux to any computer on a lan. The issue is that you can't do it remotely. Not all versions of linux can easily be made to pxe or gpxe boot. One could get a small distro booted that is capable and then install some vnc to it and then remote into to do any image you want.

Well, with Debian/Ubuntu and derivatives this is possible. First you need to boot PC and start installer from network, for that you need PXE server, TFTP server and WWW or NFS server (it can be embedded router if you have full control over it), then setting in clients BIOS to boot from LAN. Next you need to prepare installer files to do automatic installation: you can choose configuration, packages to install and partition hard drive, and by scripts just do anything you want. Look at documentation for information about installation from network and how to do automatic installation. If you do not want to do automatic install, you can also make installation remotly using ssh from one of PC connected to LAN, but every client installation must have own ssh session.

Then you are ready to go ...
use the g4u (ghosting for unix --- actually any OS is fine)
