Thanks for the detailed bug report. Yes it's not very clear, I'll try to
improve the comments. The idea is that when you run:

herd start guix-daemon PID

then, the guix-daemon joins the given PID namespaces, which is practical
to solve an installation issue.

If guix-daemon is started normally, outside of the installation process,
then it joins the caller namespaces, which should be a no-op. Of course,
it breaks everything if the operating system does not support
namespaces.

Fixed with 6453915cf7729203ef9552c13cb4528c6f4ed122.

Sorry for the breakage,

Mathieu
