The build step as documented actually says to download a minimal C# compiler from the mono site which is then used to compile the rest of the source to build the full system. I looked and did not find the source of this minimal compiler--so it is a black box in a way. In free software it is ideal to build everything from source. I wonder how is such a package handled in Guix? What is the strategy for bootstrapping? Thanks
