The system definition looks like this --8<---------------cut here---------------start------------->8--- (use-modules (sysadmin honeycomb)) (honeycomb-system "pankow" #:wireguard-ip "10.0.0.8/32") --8<---------------cut here---------------end--------------->8--- And I attempt to build the system with guix system build -L modules my-system.scm from within the ‘hydra‘ directory of the maintenance checkout. Unfortunately, I’ll eventually always run into this error: guix system: error: cloning builder process: Invalid argument I already tried using a more recent daemon, but to no avail. I worked around this by running the daemon with “--disable-chroot”, but that’s not great. Is this a bug? What can I do to get around it without having to disable the chroot feature? -- Ricardo
