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.
Wait, Mint switched base from Ubuntu to Debian?
'Normal' Mint is still based on Ubuntu, but there is LMDE (Linux Mint Debian Edition), which is Debian based.
Thats awesome
