Thanks for creating this post and thanks to the knowledgeable people who have responded.

I agree with adding a warning or some kind of notification.

Like you, I got this error message after (re)installing NixOS. After rebooting, however, my /boot directory is correctly owned by root. If I’m following this thread correctly, these corrected permissions mean that there’s not a persistent security hole.

I’m sure others like us will see this error message and panic a little at first until they find this thread or until an explanation is added to the installation process. 😅 So adding that notification is a great idea.
