Prerequisites

  • I have updated to the latest version using nix run --refresh github:nix-community/nixos-anywhere
  • I have reproduced the issue with the --debug flag
  • I have searched existing issues to make sure this isn't a duplicate

Bug Description

Not sure if I should report here or https://github.com/nix-community/nixos-images, but in any case, I am not able to use nixos-anywhere to install on my aarch64-linux system because the kexec fails with a kernel panic.

Steps to Reproduce

  1. Run a local qemu-system-aarch64 virtual machine. Simple instructions here
  2. Try to apply nixos-anywhere to it
  3. Observe the kexec panic

Additional Context


Have not yet fully tested on cloud servers, but I think it might be happening there too? Will update if it's clear I'm not doing anything crazy first.


Also, it seems like the installation partially completes? Boot entry is created, just not switched to immediately, and the exit code of nixos-anywhere is still non-zero.
