Ludovic, for me this is for getting agetty work correctly with the
IN-Berlin facilities for their kvm vserver redirection to the real
server.
(going off-topic:)
I plan to get them into the loop of Guix Deploy. What's the status of
that meta project by the way? I don't live in Berlin but as I don't
think if Ricardo is even remotely interested (or has the time) to meet
with IN-Berlin and introduce them to Guix on servers. My idea is
roughly to check what their requirements for servers are, their
workflow, what they'd like to see improved and use this as a feedback
for the (yet to be developed) deploy function.
Furthermore I'd like to work an intermediate way for providing GuixSD
images which fit their use case without relying on myself as a provider.
Their requirement (as I see it from my position and experience with
them) is that the users ssh-pubkey is used for machine access from the
beginning on instead of password based login. So a way to define it in
the systemconfig would be one requirement I see.
