Systemd-init has a larger attack surface compared to runit, openrc, or sysVinit.
-
Systemd-logind relies on systemd, so we need to adapt it for non-systemD distributions to ensure compatibility with certain applications like GNOME.
-
Udev also depends on systemd.

SystemD is specific to Linux, which makes porting software to *BSD even more challenging. It’s uncertain what the future holds, and there may be circumstances where Linux becomes unusable for you (e.g., compatibility issues with your laptop). Having a good alternative that doesn’t require relearning everything is generally beneficial.

SystemD-based distributions often come with more than just “systemd-init.” They include additional components like logind, resolved, networkd, systemd-timers, etc. However, many people still prefer using the alternatives they were accustomed to before systemd became popular, such as dhcpcd and cron. Consequently, having both sets of tools installed can increase the attack surface.
There is no such thing as a perfect OS where there is no attack surface or dependencies.
OP, you’re absolutely right about systemd, but similar critiques can be given to nearly any underlying OS service. (Also, I’m sure this is in response to other posts praising systemd)
I’m just starting to feel like it’s a little silly to even have a conversation one way or another about these things instead of just accepting that people could and should use the tools that fit their use case scenario the best.
For most people, the stuff they gain from things (for example, systemd) outweighs the downsides.
We don’t make such choices in a vacuum. It’s important to know limitations, attack surfaces, and dependencies, but it’s important mostly for being able to choose the right GNU tools for yourself.
Nobody can tell you what the best OS/Kernel/GNU tool is to use, because that’s always deeply dependent on your specific needs for the task at hand. While PCs are “general purpose computing,” they all can have wildly different hardware and software hiccups, and only you can use your own knowledge to choose the best tools for your use-case.
What an average Mint user gains from systemd? A bit slower boot time? A bit more ram used? 50mb heavier system updates? What problems systemd solves? I use systemd, runit and openrc on different machines and I don’t face any significant problems.
