From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

This would be a fair point, if systemd wasn't more than an init system. While a service manager (init system) is included, systemd is a system manager. OpenRC, runit, and other init systems do not need to comment because their only task is to mount the necessary file systems, setup the device manager, and start daemons1. systemd as a system manager not only needs to manage services, but it also needs to manage devices, logs, the hostname, etc.
Does this mean systemd is not bloat? Not at all, but it is not as fat as you think it is. Your system could honestly be fatter without systemd if you try to replicate everything it does with external applications. Does this mean systemd should also be justified to add an optional field for your date of birth? I guess I would say it's weird on it's own. However, given the context, I believe they are doing what they can.
Maybe so, but systemd's bloated feature creep still leads to security vulnerabilities. Another systemd root access exploit was just discovered a couple of days ago.
Unfortunate. However, it seems that is snapd's fault. Here's the important part from the article:
Ubuntu configured systemd-tmpfiles to clean out /tmp after some days. That's why the issue is only present in Ubuntu systems. Therefore, systemd was doing it's job, and it just so happened to create the perfect conditions for a vulnerability in Ubuntu.
That is a fair point, actually. If there were a theoretical systemd-free Ubuntu it may just tell something else like tmpreaper to clean on the same schedule and create the same vulnerability.
