Hello Maxim,

> +   ;; Disable the metadata_csum and 64bit features of ext4, for compatibility
> +   ;; with U-Boot.
> +   (file-system-options (list "-O" "^metadata_csum,^64bit"))
>     (flags '(boot))
>     (initializer (gexp initialize-root-partition))))

ext4 man page states that ^64bit will prevent images larger than 2^32
blocks but I highly doubt that we will generate someday images that big.

I think you can go ahead!

Mathieu
