Hi RG,

thanks for the patches!

In my opinion, in patch 1 you are goading Guix to keep a reference to
.../bin/true .

coreutils is an implicit build input anyway, so no need to do that stuff.

And if you do it, it looks as if you want it to keep a reference to coreutils
at runtime (it doesn't, but just saying).  It looks more complicated, too.

Please if you update the actual package from upstream, mention that fact in
the commit log.  If the actual upstream package changes, that's a serious
change, right?  People might wanna know where that happens.

In patch 2 could have used rename-file instead of (copy; delete).

What use is having a thing both propagated-input and regular input?
(genuinely asking)

Pushed to wip-desktop with minor changes (almost none of the above except
for the (copy; delete) thing).
