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.

If you think about it for even a minute this is still a glaring cve in systemd, exposed in this case, by misbehaving snapd. systemd still needed to be patched and so did snapd.
Ubuntu configures systemd-tmpfiles to delete a snapd tmp dir, snapd runs setuid root and blindly trusts/executes files from a tmp dir it does not manage the life cycle of. Where is the flaw in systemd here?

I don't see how systemd is in the wrong here. Curious, what would you change about it?
Stop using it.
