Another small post to serve for future memory that when you are building Linux Kernel modules from external tree source, the kernel build system behaves differently. Yesterday it happened that I lost a huge amount of time trying to understand why the installation of a module was not exiting with error, when I clearly saw errors in the logs. The reason is that this is on purpose. In the build scripts for kernel installation there is this hidden gem: https://github.com/torvalds/linux/commit/f6a79af8f3701b5a0df431a76adee212616154dc Don't stop modules_install if we can't sign external modules. I have been warned.
