At the moment the field (private-key) in /etc/guix/machines.scm expects
to be a file.
When you use GnuPG authentication keys for ssh logins, you have no
pubkey file, but you have a very long pubkey which can be used with
~/.ssh/authorized_keys and similar mechanisms.

Example:

user@abyayala ~/src/guix/guix$ cat /etc/guix/machines.scm
(list (build-machine
…
(privat-key "ssh-rsa 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 (none)")

Actually this might be the wrong approach.

The key you see above is the public key equivalent to the ssh pubkey.
The private key is only in the GnuPG keyring.

Solution for this kind of situations are welcome. For now I'll use
ssh pubkeys.

Ignore the second message in this thread. I tried to provide
a possible solution which lead to the believe that this is
considered solved. It isn't. This wishlist bug is still wanted.
