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.

Actually, I'm fine with a solution that only works on a device that I control. But, failing on every device is nice as well.
Right, working on every device requires a hardware solution. I haven't encountered any such hardware yet but I do know that it is possible. Next, your second requirement makes what you're trying to accomplish impossible. Privilege escalation by definition will escalate the privilege. The problem lies in the fact that the root user is basically a god in linux. You can even wipe your system if you so desire. However, you can read more into SELinux or other similar systems. It works by basically running check on the kernel level not user level. But the only solutions I can think of will make other day-to-day tasks more of a hassle. Also, note that whoever knows how to modify the SELinux can also bypass the system. I found an answer on serverfault that points to a blog. However, I haven't read the blog yet. You may find an answer there.
Thank you!
You're welcome. I also recommends Arch Wiki on SELinux. It helps clarify a lot of things and how different it is with traditional linux privilege escalation.
Will do.
