[arch-general] Better NILFS2 Support

So here is what I needed to mess with to get it working:

Kernel:
"Version 2 of the filesystem, known as NILFS2, is included in Linux
kernel 2.6.30."
Works out of the box with the most recent arch kernel.

mkinitcpio.conf:
I just added: MODULES="nilfs2"
I wonder if this is something that can be easily added to the filesystems hook.

/boot/grub/menu.lst:
kernel /vmlinuz26 root=/dev/sda3 ro rootfstype=nilfs2
AIF would need to take this into account, but seems easy enough.

Initscripts:
I provided a patch here: http://bugs.archlinux.org/task/20260

No other troubles as far as I know. Is there anything I'm missing?

Let me know where I can help, this is an awesome filesystem. Blazing
fast and when I delete or overwrite things on accident, it's so cool
to just mount a snapshot from like an hour ago without having to set
anything up in advance, and without even unmounting my root fs.

Cheers,
Alex
