            Bug ID: 256511
           Summary: UFS assertion failure when shutting down from
                    single-user mode
           Product: Base System
           Version: CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: kern
          Assignee: bugs_at_FreeBSD.org
          Reporter: markj_at_FreeBSD.org

I built a VM image without an fstab.  At the mountroot prompt, I entered the
root partition, and the system dropped into single-user mode (because there's
no fstab).  While shutting down, I get:
