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.

Will this be an integral part of systemd, or will they release it as a separate thing? I mean, if I like it, but I'm not using systemd (I do use it, but I'm just thinking about it), could I use this run0 (horrible name) without having to buy into all of systemd?
it's just a link to systemd-run which is a part of systemd, i doubt it works separately.
but, if you use s6 as an alternative init system, s6-sudo is a somewhat equivalent aproach to how run0 works (instead of systemd-run it calls s6-ipcclient)
The article says it works by messaging systemd to run the process as the given user, rather than being a SUID binary. So it wouldn't work without systemd.
Most systems ship with systemd
They were very specifically talking about ones that don't.
