- startall now uses systemctl start (not enable --now) - stopall now uses systemctl stop (not disable --now) - add installall command (bulk install with --dry-run support) - add uninstallall command (bulk disable+remove in reverse order) - fix docker ExecStart to use -a flag so the process stays attached - prefix ExecStop with - so a stop-on-already-dead container does not fail the unit
