System was working properly.  Then on start-up it ended up with
a screen showing  (initfamfs  --  Enter  'help' for a list of
built-in commands).  Also Run fsck  MANUALLY without  -a  or  -p
options.
How do I get into util-linux 2.33.1 to run  fsck  ??
Please let me know how to proceed to get the system running.
Thanks.
