Author: cy (ports committer)

New Revision: 189267
URL: http://svn.freebsd.org/changeset/base/189267

Log:
  Verify that the filesystem being referenced in fstab is indeed a UFS
  filesystem. This avoids confusion with nullfs and unionfs filesystems
  which reference the root of a UFS filesystem as a target.
