 The hard part is dealing with crappy third party build systems and huge dependency chains.
 * it is written in Make and Bash rather than Python like LKMC
+* it downloads packages from upstream mirrors rather than having its own copy of them. Therefore, whenever https://github.com/cirosantilli/linux-kernel-module-cheat/issues/165[some random French research institute decides to break links, your build also breaks]. This is not acceptable. There are some mirroring options: https://risc-a-day.blogspot.com/2015/10/creating-local-mirror-for-buildroot.html but it's not on by default it seems, Buildroot has to have their own official and default mirror of everything.
 
 This repo basically wraps around that, and tries to make everything even more awesome for kernel developers by adding the capability of seamlessly running the stuff you've built on emulators usually via `./run`.
