If you want to test your build before copying it into a USB stick, you can try it out on your machine using a tool like QEMU.
Please keep in mind that a virtualized environment does not provide the same amount of security as an ephemeral system (see *Prepare environment* above).
Here is an example QEMU invocation after placing `yubikeyLive` in `result/iso` using the above `nix build` command:
```console
# Launch with 4G memory, 2 CPUs and KVM enabled
qemu-system-x86_64 \
-enable-kvm \
-m 4G \
-smp 2 \
-drive readonly=on,media=cdrom,format=raw,file=result/iso/yubikeyLive.iso
```

If you want to look at every process's command line arguments you can use `ps axjf`. This prints a process tree which may have a large number of lines but should be easy to read on a live image or fresh install.
