Check NixOS configurations / eval-hosts (pull_request) Successful in 10m33s
Two bugs prevented nixos-rebuild switch from working on lxc-* hosts after
first boot, both confirmed live on a deployed lxc-tor-relay container:
1. Ordering bug: preserveSshHostKey had no explicit deps, so the topological
sort placed it at position 7 — after etc at position 5. By the time it
tried to save the SSH key, etc had already removed it as "obsolete"
(absent from the current generation's environment.etc when built without
NIXOS_HOST_KEYS_DIR). Consolidate all four system.activationScripts entries
into one block and add etc = { deps = ["preserveSshHostKey"]; } and
setupSecrets = { deps = ["restoreSshHostKey"]; } to enforce the correct
save→etc→restore→sops chain.
2. No boot-time secrets: /run/secrets is a tmpfs cleared on every reboot, and
sops-nix does NOT generate a boot-time service in this configuration
(confirmed live: no sops-nix.service in systemctl list-unit-files).
Add nixos-lxc-sops-reinstall.service, modelled after sops-nix's own service
placement (wantedBy/before sysinit.target, DefaultDependencies=false), so
secrets are reinstalled before basic.target on every non-first boot.
ConditionPathExists skips it on first boot; nixos-lxc-first-boot-activate
handles that case.
