ChangeLog, mke2fs.c, tune2fs.8.in, tune2fs.c, util.c, util.h:

Browse Source 
tune2fs.c, mke2fs.c, util.c, util.h (print_check_message): Move the
  	message which displays how often the filesystem will be checked from
  	mke2fs into a utility subroutine.  Then cause tune2fs to call that
  	function to display the message after adding a journal to a
  	filesystem.
  mke2fs.8.in: Add manual page fixups and explanation for why it's good
  	to check filesystems periodically from Andreas Dilger.

Staggering the mount-counts at which filesystems are forcibly
checked will avoid all filesystems being checked at one time
when using journaled filesystems.
.sp
You should strongly consider the consequences of disabling
mount-count-dependent checking entirely. Bad disk drives, cables,
memory, and kernel bugs could all corrupt a filesystem without
marking the filesystem dirty or in error. If you are using
journaling on your filesystem, your filesystem will
