bug#56669: enhancement: Link guix system and guix home

[Dale Mellor]

I would like to be able to create a rescue disk for my system in which
the admin user's home directory contains a copy of an encrypted key,
for manually unlocking encrypted disk drives.

Following a short discussion in IRC, it appears the best route to
achieve this would be to link *guix system* and *guix home* together,
so that the system configuration file can specify

(user-account
   ...
   (configuration (local-file "my-home-config.scm")))

for example (it should be possible to use either (home-configuration)
or a file-like object here).

Hopefully this is an easy thing to accomplish, but I don't know...

Thanks,
Dale
