Been using systemd for at least 6 year now, and yes it is indeed quite stable.
But making startup services is hot garbage, and accessing system logs is even worse. journalctl is an unapproachable mess, and I really don’t like the idea that systemd is kind of slowly replacing the linux kernel in its entirety.
It doesnt affect my day to day as a normal user, but when I switch to power user mode its… It makes maintaining my system very unenjoyable.
We literally have /var/log/ as a well-known standard though. Almost every piece of linux-standard software dumps to a subfolder by the app name in there. Systemd should at the very least have the capability to mirror there so you can get at the logs in a sane way.
