Sometime recently it seems to have become possible to disable the
whole block device subsystem.
Though in my tests I can't quit build with it disabled.

Anyway, for an embedded device this might be appealing.
how does this interact with initramfs and flash ?

Can I boot an initramfs kernel without a block device ?
Can I write a filesystem driver for a flash device that does not
require a block device ?
Are their any examples of something even close ?

For that particular flash case there's just jffs2 in the kernel tree,
with some more flash filesystems under development. You can of
course have network and in-memory filesystems aswell.
