Re: [Buildroot] [PATCH 3/3] fs/dracut: new fs type

Thierry, All,

On 2021-12-17 22:50 +0100, Thierry Bultel spake thusly:

Good idea. But dracut generates a gzipped cpio image.

That the cpio is gzipped is unfortuante, because the kernel will again
compress it as part of its own compression (whem it is used as an
initramfs, IIRC).

Maybe, instead, the
"cpio" and "dracut" options (exclusives) could be but in a "Initial RAM
filesystem" menu.

We already have such a filesystem:
    fs/initramfs/
        "initial RAM filesystem linked into linux kernel"

And this one is tricky, because it hooks into linux/linux.mk with manual
and custom dependencies (see linux/linux.mk@571). I am not 100% happy on
how this is done, but we can't really have better...

So, I think that having dracut be an option of cpio is the easiest way
to go...

Yann E. MORIN.
