Check NixOS configurations / eval-hosts (push) Failing after 11m15s
boot.isContainer disables services.udev, which NetworkManager depends on to enumerate devices — this left NM unable to reliably manage the container veth, breaking DHCP-hostname registration in Pi-hole. It also defaulted networking.useHostResolvConf to true, which assumes a systemd-nspawn-style resolv.conf bind-mount that real Proxmox LXC doesn't provide (nixpkgs' own proxmox-lxc.nix module forces this false for the same reason). Also guard the networkmanager extraGroups membership in the minimal/gui build-types, since that group only exists when NM is enabled.
