## 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.
