##  Notes:
##    This set of tests creates a dummy directory tree in /tmp and
##    populates it with several files.  The test requires around 1100
##    inodes and 6.8MB.
##
##    This test verifies that newfs can create filesystems in both bytes
##    orders. For each byte order it is checked that:
##      - the kernel understands both filesystems created
##      - fsck_ffs can convert them from one byte order to the other
##      - dump handles properly the 'nodump' flag, an that restore can
##        properly restore the filesystem.
##
##    This is derived from work done by Brian Grayson, submitted in PR 6706.
