I already have host/foreign distro's "nscd" package installed, and the
daemon was/is already running.

- Distro: Trisquel 7

- nscd version: (Ubuntu EGLIBC 2.19-0ubuntu6.14) 2.19

--8<---------------cut here---------------start------------->8---
$ sudo service nscd status
[sudo] password for adfeno:
 * Status of Name Service Cache Daemon service:
 * running.
$ LANG=C sudo netstat -lanp | grep nscd
unix  2      [ ACC ]     STREAM     LISTENING     18682    1349/nscd           /var/run/nscd/socket
--8<---------------cut here---------------end--------------->8---

I also made my own "/etc/nsswitch.conf" file, which is attached. The
"nscd.conf" --- also attached --- comes from the "nscd" package, and
wasn't changed by me. If I recall correctly, the only think that I made
myself was the nsswitch.conf file, in which the "hosts" entry was based
on GuixSD's related GNU Shepherd service.

I also took care to restart the Guix daemon after changing the
nsswitch.conf file, but got the same result.
