Use glorious nixos. Never fear anything breaking. And even if you manage to do so just roll back in the boot menu or terminal.
Ahh until something hangs when updating grub. Had it happen twice over the last couple of months. No real biggie as it’s not the hardest thing to recover from / easy enough to pull my config and rebuild.
Maybe it’s me, maybe it’s Nixos or Grub.
Why would you update grub?
Also I am not sure if I am even using grub. Does systemd have a bootloader?
Normal people don’t change their bootloader that often.
Yeah, systemd-init. Pretty sure the GUI installer uses systemd-init – never broke once for me.
