Ozone — The J-Link Debugger and Performance Analyzer
Ozone is a cross-platform debugger and performance analyzer for J-Link
and J-Trace.
- Stand-alone graphical debugger
- Debug output of any tool chain and IDE 1
- C/C++ source level debugging and assembly instruction debugging
- Debug information windows for any purpose: disassembly, memory,
globals and locals, (live) watches, CPU and peripheral registers
- Source editor to fix bugs immediately
- High-speed programming of the application into the target
- Direct use of J-Link built-in features (Unlimited Flash
Breakpoints, Flash Download, Real Time Terminal, Instruction Trace)
- Scriptable project files to set up everything automatically

This is a program that just displays a static cat picture in a Wayland
window. I packaged it a while ago thinking it wouldn't be useful for
anybody else, but a conversation on IRC today made me realise it would
be!
hello-wayland is very useful as a minimal example when hacking on
Wayland ecosystem stuff -- even if Firefox doesn't work yet,
hello-wayland probably will and that can be useful to guide you in the
right direction!
(The first version of this change, in commit 39fad297fd, broke
`nix-build -A nixosTests.installer.simpleUefiSystemdBoot`. This is the
2nd version, which hopefully does not break anything.)
`nixos-rebuild build-vm-with-bootloader` currently fails with the
default NixOS EFI configuration:
$ cat >configuration.nix <<EOF
{
fileSystems."/".device = "/dev/sda1";
boot.loader.systemd-boot.enable = true;
boot.loader.efi.canTouchEfiVariables = true;
}
EOF
$ nixos-rebuild build-vm-with-bootloader -I nixos-config=$PWD/configuration.nix -I nixpkgs=https://github.com/NixOS/nixpkgs/archive/nixos-20.09.tar.gz

Fix it by setting virtualisation.useEFIBoot = true when needed.
