Usage: sudo scripts/update-systemd [options]

Refresh an existing native pobsync systemd install from the current checkout.

This is a thin, safer update wrapper around scripts/install-systemd. It keeps
the install non-interactive, preserves the existing environment file, skips
superuser creation, and skips OS package installation by default.

Common options are forwarded to install-systemd, for example:
  --source-dir PATH
  --app-dir PATH
  --venv-dir PATH
  --env-file PATH
  --service-user USER
  --service-group GROUP
  --install-extras mariadb
  --verbose

If OS packages need to be refreshed, run scripts/install-systemd directly.
