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.

Enabling secure boot later on (lemmy.ml)

So, I've installed Manjaro quite while ago, and I let secure boot disabled during installation. Dang! Is there a way to keep (most of) my system and enable secure boot and LUKS after the fact?

I have since replaced the hardcoded values with variables, but evidently haven't pushed the changes to gitlab. Having said that - not having variables might make it easier to understand in this case.
