Yes, they are included when "guix shell ..." etc.
BUT they are not included when "sudo guix system reconfigure ..."

bug#62698: bind:utils

[Brian Cully via Bug reports for GNU Guix]

With the config below, I have ‘host’, ‘dig’, and ‘nslookup’ in my
path. Note that I'm using the ‘(compose list
specification->package+output)’ form, though. If you're not using that,
you may be accidentally loading the ‘bind’ package with the default
‘out’ output, instead of the ‘utils’ one. If that's the case, then
you're not going to have the utils in your PATH because they haven't
been installed.

Well, I use this:

  (packages
     (append
       (map specification->package+output
          '("bind:utils" ... ))
     %base-packages))

But I am new to scheme/guile/guix, so maybe I do something wrong. Anyway,
thanks for confirming that it works on your side. It's probably an issue
with my configuration. :)

I suspected this was the problem. You really do need to use:

(map (compose list specification->package+output)
     '("bind:utils"))

Because ‘specification->package+output’ returns two values, and 
you'll need to combine those into a list for the second value (the 
‘utils’ output) to be seen.

Thanks for finding the problem.  Should we leave this bug open until
specification->package+output is properly documented in our manual, with
an example?  If yes, would you like to try your hand at adding it?

I've looked at this briefly, and can't figure out a good place to 
document this (I'm also not particularly good with TexInfo).

I'm okay with closing the bug. Though I will say that I think this 
procedure is a bit of a foot-gun. Multiple value returns are 
always kind of weird, and in this particular case I don't see the 
value at all; the only reason to use 
‘specification->package+output’ would be to get both the package 
and the output, so the minor advantages of multi-value returns are 
obviated. On top of that, does this even get used outside of 
system/home definitions? And in those places you always want a 
list.

I realize a lot of code uses the current semantics, so changing 
them would be extremely difficult at this late stage. It's worth 
thinking about adding another procedure that does the expected 
thing (returning a list of package and output), IMHO, and 
transitioning over to that.

Hm, looking at '(guix) Packages with Multiple Outputs', we already have
an example, which simply append packages and (list package "output")
lists, so perhaps that should be preferred instead.  The
'specification->package+output' procedure mostly appears to be used
internally, in (guix scripts environment) for example.

Note that for user profiles, it seems better to use manifest with the
convenient 'specifications->manifest' procedure that allows directly
providing package name/outputs via a "bind:utils" specification, for
example.

Closing!
