IN-Berlin wants a raw image (they have read our documentation).
The way their system works is that you sent
them your ssh pubkey, they initialize a basic Debian system depending on
the size you chose, and you can login once you get the hostname etc.
They have an out-of-band consoleserver where the ssh key is placed
aswell for the machine.
I don't work with this non-profit organization, but having a way to
define ssh pubkeys in the system config would be super useful for this.
Right now I'm about to create my own system and just sent it to them as
soon as I feel up to it.
If they could simply create the system in their infrastructure, that
would be an incredible speedup and reproducible.
I don't know much about the out of band consoleserver, I have to ask
if that's somehow relevant or if it simply needs some initrd settings to
expose it to the server.
