Whatever — the + │ main costs are: the 2-sec-per-attempt systemd permission delay and the 1.3-sec list-unit-files. + │ + │ Improvements: + │ 1. **Cache the privilege mode**: once a privileged operation succeeds (or fails as plain due to + │ permission), remember that sudo is required. In practice, more simply: detect at startup whether + │ the plain `systemctl start/stop` is permitted (test with `systemctl is-system-running`? No, + │ that's read-only).
