I wanted multiple times to study the OpenBSD source code and I&#x27;ve downloaded it but I never managed to navigate through it, to find the &quot;head and the tail&quot; or to find a reasonable &quot;map&quot; of the source code. I would like for example to follow the execution path in the source code, from the boot up to the login prompt. Does any documentation like this exist or could anyone give me some hints ? Thanks
