Well, the fact my window manager is now intrinsically linked to my systems boot process strikes me as somewhat obscene. There was the amusement with it reacting to debug being passed to the kernel which caused the system to never finish booting...

systemd is by no means alone; in the last month I've discovered that `yum` deliberately breaks its output when you try and pipe it to something else (I mean really, ffs, really?). The justification for this isn't even internally consistent which really winds me up too...

Whilst I pick on a couple, there's been innumerable packages, languages and platforms over the years that have had their share of what could politely be called idiosyncrasies. I highly recommend The Unix Haters Handbook [1] for plenty of historic examples -it's a lovely read -oh, and for years one of the *nix bullet points was always "all the power in the world and not a safety in sight" [2]
