Beware nixos-rebuild changes in NixOS 23.11 release (https://github.com/NixOS/nixpkgs/pull/258571). Namely:

nixos-rebuild {switch,boot,test,dry-activate} runs the system activation inside systemd-run now, creating an ephemeral systemd service and protecting the system switch against issues like network disconnections during remote (e.g. SSH) sessions. This has the side effect of running the switch in an isolated environment, that could possible break post-switch scripts that depends on things like environment variables being set. If you want to opt-out from this behavior for now, you may set the NIXOS_SWITCH_USE_DIRTY_ENV environment variable before running nixos-rebuild. However, keep in mind that this option will be removed in the future.
