Glad you like it, and sorry for the late answer. > substitute: guix substitute: warning: 10.0.0.5: connection failed: No route > to host Once your laptop goes to sleep, Avahi should detect that the publish service is gone and remove it from the cache at /var/guix/discovery/publish. I'm having troubles reproducing it at home. Could you please run "avahi-browse -a" on your desktop, put your laptop to sleep, and check if the publish server disappears this way: --8<---------------cut here---------------start------------->8--- - enp7s0f0 IPv6 guix-publish-cervin _guix_publish._tcp local - enp7s0f0 IPv4 guix-publish-cervin _guix_publish._tcp local --8<---------------cut here---------------end--------------->8--- Regarding the reboot issue, that's because the cache wasn't cleaned-up, it should by fixed with: ee94cd265e03d12eeeccf58cbaf74b90008fcd14. Thanks, Mathieu
