You have a point here, I guess with initramfs you have to:
- use devfs (which was deprecated in 2.6)
- use udev
- grok-sysfs-yourself (which is pretty easy)

Well, the same way as with the good old-initrd. the initramfs root-fs
IS an INITRD in compressed-cpio format (instead of fs format such as
ext2).
me think I'm still missing something about initrd.
