We should avoid the Git protocol if possible, preferring, first,
tarballs and, second, HTTPS or HTTP Git URLS. Is that possible for this
package? The Git protocol depends on access to an unusual port, and it's
not private or authenticated.

Is this just for sysvinit? If so, can you add a comment saying so? Or
explain the context of the patch a little more?

How about calling this phase "install-docs" or "install-contrib-docs"?.

Setuid Guix only exists on Guix System, so we should drop this wrapper.
It's okay to make users do `sudo wg-quick` or similar.

Is coreutils not already available in the build environment?

IIUC, we don't need to include Bash in both 'native-inputs' and
'inputs'. If this Bash will be used at run-time (e.g. as a script
shebang), we should just use 'inputs'.

Switched to tarball.

Explained in the patch: it needs to know how to restart nscd so this
patch add support for doing so with shepherd when on a Guix System.

Replaced '=' with 'prefix' and dropped "/run/setuid-programs" from the 
wrapper.
