An fsck that fails with "UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY."
should cause the boot process to stop right there and drop to
single-user mode. Under 4.x, it will run fsck -p on any dirty
filesystems, and only if the preen returned success on all filesystems
will it continue to multi-user mode. 5.x is a bit more lenient, since
it can clean softupdates filesystems in the background.
