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 is worse than many, since it persists across reinstalls and even potentially drive swaps, and fools systems such as secure boot.
If it's only on the ESP, it won't persist across reinstalls, and definitely not drive swaps.
But I do see mentions of attacking via firmware capsule. If that works, then yes, that will persist.
ESP is usually not cleared on a reinstall unless somebody takes the extra step to do so. Since each OS has its own directory within the ESP their installers don't push it. I was mostly referring to modification in firmware though.
