Check NixOS configurations / eval-hosts (pull_request) Failing after 40m2s
Cross-host references throughout this repo (vars.nfsServerHost,
vars.nixCacheHost, vars.dockerHost) are bare short names, not FQDNs.
Resolving them has always depended on whatever network stack happens
to be in play picking up the DHCP-advertised domain as a search
suffix -- NetworkManager does this by default, which is why it went
unnoticed everywhere else, but LXC containers force-disable
NetworkManager and get their systemd-networkd config written directly
by Proxmox instead, which never sets one.
Confirmed live on lxc-docker (vmid 105) after today's earlier fix for
the automount/mount=nfs bugs: systemd-resolved had no search domain
for eth0, so "server" failed to resolve ("Name or service not known")
while "server.sweet.home" resolved fine via the same DNS server --
every NFS mount in modules/docker/mount-data.nix was still failing.
networking.search sets systemd-resolved's own Domains= globally
rather than depending on the per-link DHCP path, so it isn't at the
mercy of whichever component owns a given host's interface file.
