Indeed. In terms of getting a consistent system where you can pull in packages and drivers from different places while still being able to tweak everything in an embedded system, it's the best option out there. Not that it's a great system (bitbake, the meta-build system, is a bit of an arcane horror. If I were to reinvent yocto, I would use something like nix, which bitbake sort-of tries to be like but fails).
