Hello!

Okay, after overcoming completely unreleated troubles I finally managed
to reconfigure a laptop to hurd-team to test it.  It works great!

Yes, works beautifully.

That also works nicely.

I found that by default, only root can offload.  Is that intentional,
how would that work?  I changed permissions on
`/etc/guix/offload/ssh/childhurd' like so

--8<---------------cut here---------------start------------->8---
$ l /etc/guix/offload/ssh
total 8
-rw-r--r-- 1 root root   93 Sep 23 14:47 childhurd.pub
-rw-r----- 1 root wheel 399 Sep 23 14:47 childhurd
--8<---------------cut here---------------end--------------->8---

to "fix" that. WDYT?

Found another two commit message nitpicks

Remove "add".

Rather use 

(hurd-vm-configuration-offloading-ssh-key,
hurd-vm-guix-extension): New procedures.

?
