bug#34580: Service ssh-daemon could not be started

[Andreas Enge]

Hello,

twice in a row at work (on harbourfront) and now twice in a row at home
(on dover) I am in a situation where sshd does not start on Guix machines.
Networking is available (the machines can be pinged), and I have to log
in via a console and execute "herd start ssh-daemon" by hand.

Here is the relevant portion of /var/log/messages for dover:

Feb 19 22:03:48 localhost shepherd[1]: Service ssh-daemon has been started. 

Besides the notice that "Service ssh-daemon could not be started" I do not see
much information. The second time corresponds to the starting by hand.
Maybe it is a problem that " sshd[359]: Server listening on 0.0.0.0 port 22."
at 22:02:10 before the IP address arrives via dhcp 2 seconds later?
