    Yeah, I agree, do you really need udevd, device file creation at every
    start-up in /dev? Usually static devices nodes and mdev for hotplug are
    enough or at least you could use a simple script to create only once
    time the devices file (mdev -s). About the fs, do you really need a
    rootfs with ubifs? I mean, you could "split" your fs. You could use a
    read-only fs (SquashFS for example) for your root-fs, ubifs for
    permanent storage data (mounted under /data for example) and a ram fs
    for volatile data.
