+- Default to user and group `root` (UID 0) for services
+- Always check that service user and group resolve to valid UID/GID pairs,
+  otherwise log error and refuse to start service
 - Hide cursor at boot and shutdown for cleaner visual experience
+- Rename `tty` services early from `init` -> `getty` even though no getty
+  process has been started yet.  This to aid in boot timing detection using
+  tools like `bootchartd` (BusyBox version or bootchart2 project) when Finit
+  only shows *"Please press Enter to activate this console."*
 - Services with `respawn` option (including TTYs) now delay retry on non-zero
   exit codes instead of immediate respawn.  Prevents busy-loop when service
   fails repeatedly, which on some systems may have a crippling effect
