I am not the greatest fan of most of systemd's features. I will always prefer it tho since I just view it as a "packaging format". The same way I view docker. It is just that it happens to be the format that a lot of software is using and I have almost no headache integrating services, timers, logging and such of software I install. Without systemd its a mighty pain. Everyone uses the same one thing and that makes me overlook any drawbacks of the model. Only if the entire system was set up by me and mostly ran my software and I was getting paid for it, I might not use systemd.

But one feature of systemd I will absolutely stand by is nspawn. It's just beautiful.
