I found it with the search tool:
http://lists.gnu.org/archive/html/guix-devel/2017-03/msg4.html
It's weird that it wasn't linked to the other messages.

I my inbox I have a reply from Andy saying:

I’d suggest you ping Andy on IRC or simply push them!

Done, applied to master as eba560765a5afccbc5d3b64df410d89b1f79a18e.

There are two other patches concerning services:
http://lists.gnu.org/archive/html/guix-devel/2017-02/msg01154.html

Please, could someone do a review on these? :)

Thanks!
Clément

Well, maybe here "lmtp" is not the section name, but the path, relative
to "base_dir".  Sould I update the documentation to specify that "path"
may be relative to "base_dir" too?

But anyway there's still the bug, because relative paths don't start
with "/".

Yes, because the path is also used as the section name (see
http://wiki2.dovecot.org/Services#Service_listeners).

So for example, this code (from gnu/services/mail.scm:445) raises an
error because "lmtp" doesn't start with "/":

(service-configuration
 (kind "lmtp")
 (listeners
  (list (unix-listener-configuration (path "lmtp") (mode "0666")

I don't understand how it could work before.  Maybe the check wasn't
done.

Why's that?  Is the extra checking from the file-name type (that the
string start with "/") getting in the way of something?
