When I move with my Guix laptop, I frequently get domain name resolution
errors.

To fix the issue, I need to run

--8<---------------cut here---------------start------------->8---
# herd invalidate nscd hosts
# herd restart nscd
--8<---------------cut here---------------end--------------->8---

The issue is fixed as long as I don't move again.

This is impractical and the solution is very much non-obvious :p
