Good idea!

I think this should rather go to “Invoking guix publish”, to avoid
making “Binary Installation” too intimidating (and because users do not
initially care about running ‘guix publish’).  WDYT?

Also, I think it would be enough to add a cross-reference to “Invoking
guix archive” where we mention that a key needs to be generated.

Last, I think we should simply recommend user ‘nobody’, which we can
expect to be already present.  It does the job and will make the
instructions shorter.

WDYT?

The rest LGTM, thanks!
