Yes, `apt-get install nscd` does everything necessary to set up and
start nscd, and then guix-daemon works.

This guix-daemon is based on core-updates commit 76ef53eb828 (gnu:
glslang: Update to commit b5b084624), on x86_64-linux.

It's linked against
/gnu/store/n6acaivs0jwiwpidjr551dhdni5kgpcr-glibc-2.26.105-g0890d5379c.

nsswitch.conf looks like this:

$ ls -l /etc/nsswitch.conf 
-rw-r--r-- 1 root root 529 Jun 13  2017 /etc/nsswitch.conf
$ cat /etc/nsswitch.conf 
# /etc/nsswitch.conf
#
# Example configuration of GNU Name Service Switch functionality.
# If you have the `glibc-doc-reference' and `info' packages installed, try:
# `info libc "Name Service Switch"' for information about this file.
