During shutdown, Finit unmounts tmpfs and remaining regular filesystems.
Currently,
unmount_regular()has no return value, so shutdown alwaysreports success for "Unmounting filesystems ...".
On systems with busy or otherwise un-unmountable filesystems, this hides
failures and makes shutdown-related mount issues hard to diagnose.
Return a failure status from
unmount_regular()when filesystems remainmounted, and use it to report the final shutdown unmount result.
