Things get really complicated when you put a linux kernel and userland
in flash... where you have to download dozens of files, with odd
dependencies.

But with simple payloads like seabios or filo, it doesn't seem to be
black magic.

I do like the idea of always building on a clean checkout. If this means
to really rm -rf the source tree, something sounds severely broken.
Buildroot certainly is, but it's running on a multitude of platforms
with a multitude of applications, so they clearly have a different scope
than we do

I find it quite non-trivial to get this right. Just defining coreboot to
be this payload free (thus, unusable as is) piece of rom code is also
not nice at all.
