No, it's mostly awkward for the people reading linux-kernel.
Linux-kernel is a very high volume mailing list, and proper use of
email threading is *vital* to read it: you immediately get all
references to previous messages, and it makes it easy to skip threads
you're not interested in (nobody except Alan Cox and his gnomes reads
every message to linux-kernel).
If you're not subscribed, the normal way is to:
- Ask to be Cc'ed (that usually happens anyway).
- Reply to the sender, the list, and everybody else in the Cc list.
- Keep In-Reply-To and References headers so the other subscribers know
what to read and what not.

It would never occur to me to use something as inappropriate as a web
browser as a mail client...

It hasn't for good reasons. Read the LKML FAQ at http://www.tux.org/lkml/ .

Please do so. It will certainly help you to get more/different replies.

The kernel people prefer cpio because they have experience with it, it
doesn't need too much code, and it works.

You've been told that there are *technical* reasons not to use tar in
the kernel. The kernel developers never cared about what was most used
or what "the market wants", but only about what was *technically* useful.

Initramfs using ramfs *is* comparable and it *has* a filesystem.

Did you ever take some time to actually *understand* what ramfs is,
*why* it is used for initramfs, and why you can't use any filesystem
you like for an initramfs?

Read the code, ramfs *is* comparable to the old initrd method, and
tmpfs is the same as ramfs with the difference that its pages can be
swapped out.
> Initramfs is already ahead of the old initrd method on other levels.
It is, but mostly because it makes the kernel boot procedure so much
easier and removes a lot of special cases in the code.

You have used both, so why is tmpfs a "robust filesystem" and ramfs
not? Again, what is your definition of a "robust filesystem"?

"Doctor, it hurts when I do this!" "Well, then don't do that."
You found a nice case of "Unix, rope, foot".

PS: I'm not going to hunt through my linux-kernel mailbox for replies
without proper In-Reply-To and References headers in the hope that I
stumble over a possible reply from you. Any reply without such
headers will most probably not been seen and just ignored.
