Hi,

> Sounds like this ssh URI is not valid on the nodes, is that right?
I would consider it valid, since `ssh master.<domain>` and `guix build
<package>` both work just fine from the nodes. It’s just `guix pull`, which is
causing issues.

Sure, that’s an option, but anyone who tries will get a strange error message.
And it breaks the appeal of having a remote guix daemon in the first place,
that is being able to run `guix <whatever>` on any machine I log into. If that
is not the case (i.e. not for `guix pull`) it would be more consistent to ask
users to SSH into a different machine every time they interact with guix. Does
that explain my use case?
