I have changed the way that soft dependencies are enabled and disabled.
This is now done via a mount option (-o softdep). It can no longer
be done via tunefs, after you have recompiled it.

If you are using soft dependencies, and want to upgrade your kernel,
you should:

	1) compile a new kernel
	2) boot it single user
	3) use the old tunefs to disable soft dependencies on any
	   filesystem you may have set it
	4) continue booting
	5) enable the softdep option in /etc/fstab for the filesystems
	   that you want it to be active on.
	6) reboot again

Note that you currently can not use -o softdep with the -u flag if
you are doing a mount update on a writeable filesystem. This has to
do with how the softdep code is structured. This might be fixed
in a future release of NetBSD.
