Just to be clear, the message we now have is:
service 'ssh-daemon' requires 'networking', which is not provided by any
service

So I think you’re saying that, in addition to the error message, you’d
like suggestions.
I like the idea. However, in this specific case, I’m not sure how to
achieve it: ‘guix system’ doesn’t know about all the Shepherd services
that can possibly exist, so it cannot tell you that the ‘networking’ is
provided if you add ‘dhcp-client-service’ or whatnot to your config
file.
I understand these are not details one cares about as a user, at least
at first glance. But this limits what we can do.
Thanks,
