New Revision: 316800
URL: https://svnweb.freebsd.org/changeset/base/316800

Log:
  MFC r316593:
  
  Point out that -F probably does not do what the user expects.
  
  Users attempting to create images from mtree METALOG files created by
  installworld often use -F when they should be passing the METALOG file
  in place of a directory. This is often produces difficult to debug
  error reports.
