[arch-general] Moving the root filesystem to a multipath device

[Ary Kleinerman]

Hi there,
I'm working with a EMC Fibre Channel storage and I need to move the root
filesystem to a multipath device. Ubuntu has a package named
"multipath-tools-boot" that modify the initramfs and adds the script,
modules and binary for multipath.
I do not know much about mkinitcpio, but I think I need a hook for
multipath. Can someone help me with this?
Regards,
Ary
