Systemd is not 1 giant thing that does 100000 things - it is a collection or 10000 services doing 10000 things, integrating amongst themselves where practical. You need not use networkd, logind, resolved or any other one piece of the system you dislike.

My least favorite part is journald. When you find a way to rip that out, let me know.

Also logind is so hard to avoid that even other systems have ported it: https://wiki.alpinelinux.org/wiki/Elogind
