Definitively sounds better, especially when seeing it from that
perspective!

I tried to keep the message rather short at first, since it is printed
on one line currently. But we could also use "{err:#?}" as format
specifier below, to let anyhow break up the error message over multiple
lines.

I'll send a v2 shortly!

No, currently not. But I already talked with Michael about more
extensive validation in the future, in both the auto-installer and
auto-install-assistant.
