>Description:
	rc.subr does not mount zfs datasets in sorted order
>How-To-Repeat:
	Multiple zpools - e.g. one with /usr/pkgsrc, another with
	/usr/pkgsrc/distfiles
	Crapshhot as to which is mounted first, resulting in perhaps distfiles
	being on the former
	Sorry about severity - critical for me - but probably not common
>Fix:
	add | sort after zfs list -H -o in /etc/rc.subr - sorted mountpoints is
	the correct order
