Does it have to go through the store? I imagine key generation would be
done by the installer, not guix system init. That would be much in the
same way that the installer creates partitions, while system init (or
reconfigure) doesn't touch partitions, only uses existing references.
In that sense, the installer would create the file from /dev/random or
urandom and place the reference in operating-system.

It would also allow manual installations to retain flexibility
configuring encryption.
