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
(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...
