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.

Overview: How UEFI Secure Boot Works in Linux (tiffybelle.vivaldi.net)

Been down the rabbit hole lately of UEFI Secure Boot issues, and decided to write an overview of how it works out-of-the-box in the excellent Debian-based Linux Mint LMDE 6.

Have mostly been researching this stuff as I was looking to replace GRUB entirely with systemd-boot on one of my systems. Will likely write a follow-up piece documenting that journey if I think it'd be interesting to some nerds out there.

What is the point of secure boot, if secure boot will boot a shim bootloader which will then boot whatever else you want?

All the marketing and hype.

I think the shim bootloader as well as the booted software must perform some verifications too.
