BOOT SPACE ERROR

If you are out of space on your /boot partition then follow the steps in the section below

• Remove systemd boot, ideally this should be done automatically when systemd-boot is turned off, but 🤷.

bootctl remove

Then:

sudo rm -rf /boot/loader

Fix for /boot being out of space

Rebuild but don't switch and store that config

sudo nixos-rebuild build

Run a garbage collection to remove the old system generation

sudo nix-collect-garbage -d

cd into /boot/kernels/

cd /boot/kernels

List the files and then delete any old kernels, DO NOT DELETE NEW ONES, BE VERY CAREFUL Rebuild and switch

sudo nixos-rebuild switch

Now reboot
