Thank you!  It looks good to me.  I've queued it locally with the 
(minor) changes below, but will wait a few days for 
<https://issues.guix.gnu.org/41579> to land if that's all right 
with you.  I also need to test it as a proper setuid programme.

I've added a newline after ‘arguments’ to give your phases (and 
helpful comments) some room to breathe and keep lines from 
exceeding 80 characters.  It's mainly a matter of preference. 
Since I'm reviewing this so you're stuck with my preference.

I shortened this to the last sentence and added a full stop here…

…and here.  ;;-style comments are full sentences, unlike ;-ones.

All true, but so common a change in Guix that it's not worth a 
comment.

Phases need to end in truth so I've added a #t here.  We get away 
without one in the previous phase because INVOKE itself is 
guaranteed to return #t.

It didn't look to me like this was used for anything, and quoting 
Morgan on IRC:

<butterypancake> ya, the configure script really doesn't do a damn 
thing with target. But in the future it might save someone some 
time.

I agree that it's nice to save future maintainers the trouble of 
retracing your steps but don't like the idea of sleeper code. 
I'll keep them as comments.

Changed to the equivalent but more conventional

         #:tests? #f)))                 ; no test suite

> +    (native-inputs `(("bison" ,bison)))

Added a trivial newline before `.

Thanks for including a multi-line description!  Won't stop me from 
trying to expand it some more.

Not surprisingly, libbsd/ is under a 3-clause BSD licence.  I 
added it.

This would be a separate patch.  However, this would install doas 
on almost all systems.  I think the default list should contain 
only the minimal defaults, and I don't see doas being a must-have 
%base-package any time soon.

Kind regards,
