Some of those jokes are very funny. I really liked the one about how systemd is modular, just in the same way that the Linux kernel is modular, because you can compile it with all different options.
1) This is actually modular. I mean... those things are even called "modules".
2) Even if it wasn't modular, how would it matter? You're comparing to the Linux kernel. If that one isn't modular then according to you, systemd also isn't modular. Allright, so be it, did you have any problems with missing modularity in the Linux kernel lately?
