Howto set norelatime on f15 root?

[Neal Becker]

F15beta running in vm.

I changed /etc/fstab to say:
/dev/mapper/vg_nbecker6f15-lv_root 
/                       ext4    norelatime        
1 1
UUID=768e1633-a96b-4932-832b-f65778b51627 /boot                   ext4    
defaults        1 2
...

But according to mount, norelatime was ignored.  2 questions:

1) What do I need to do to get norelatime?
2) I see /home mounted, but there is no entry in /etc/fstab.  Who mounted 
/home, 
and how can I change options?

(also tried running dracut, but still see no diff)
