GuixSD automated installation

[Ian Eure]

Hello,

On Debian, you can create a preseed file containing answers to all 
the questions you’re prompted for during installation, and build a 
new install image which includes it.  When booted, this installer 
skips any steps which have been preconfigured, which allows for 
either fully automated installation, or partly automated (prompt 
for hostname and root password, but otherwise automatic).

Does Guix have a way to do something like this?  The declarative 
config is more or less the equivalent of the Debian preseed file, 
but I don’t see anything that lets you build an image that’ll 
install a configuration.

I see there’s `guix deploy', but that requires an 
already-installed GuixSD to work, which isn’t helpful for getting 
it installed in the first place.

Thanks,

 — Ian
