First of all, I think it is a very interesting presentation. It should
definitely become part of the official buildroot documentation, so
that companies starting with buildroot get a better feeling about the

p 11: "Buildroot builds a toolchain. This is limited to uClibc based

I think this is confusing: to me it gives the impression that the
toolchain is rebuilt at every invocation of 'make'. Maybe adding the
word 'complete' as with crosstool-ng makes it more clear.
p 14: "Generate a custom toolchain, and store it pre-built next to the
Buildroot directory, or in some internal HTTP server"
It could be anywhere on the filesystem, plus doesn't buildroot support
FTP either? Moreover, patches are coming to add scp support as well.
My point is that mentioning 'http' explicitly is maybe too
p27: It's a pity that the dependencies don't fit completely in the
box. Maybe use MY_APP instead of MY_APPLICATION or something?
p28: "storage in configs/": I think it would be better to explicitly
mention that the file 'defconfig' should be stored in configs/
p30: Future: would you consider mentioning that support for Mercurial
repositories and 'scp' downloads for LAN-based locations is in queue?
As I side note : I read that you use /rootfs-additions/ to add
additional stuff in the root filesystem. I'm doing exactly the same
thing (called target_skeleton_extras). I feel this may be a good thing
to officialize: let the user specify an overlay to the target
skeleton. What do you think? (we may want to discuss this in a
Good luck with the presentation!
