be able to build it in situ, so the build process is based around
"cross-compilation" from another computer. The build machine can be
any reasonably powerful desktop/laptop/server PC running NixOS.
Standalone Nixpkgs installations on other Linux distribuions or MacOS
also ought to work (but I haven't tested that configuration)

You can do this without even having a router to play with.

In this command ``liminix-config`` points to the configuration for the
device (services, users, filesystem, secrets) and ``device`` is the
file for your hardware device definition. ``outputs.default`` tells
Liminix to build the appropriate image output appropriate to
flash to the hardware device: for the qemu "hardware" it's an alias
for ``outputs.vmbuild``, which creates a directory containing a root
filesystem image and a kernel.
In this command ``liminix-config`` points to the desired software
configuration (e.g. services, users, filesystem, secrets) and
``device`` describes the hardware (or emulated hardware) to run it on.
``outputs.default`` tells Liminix that we want the default image
output for flashing to the device: for the Qemu "hardware" it's an
alias for ``outputs.vmbuild``, which creates a directory containing a
root filesystem image and a kernel.

This starts the Qemu emulator to run the Liminix configuration you
just built. It connects the Liminix serial console and the `QEMU
monitor <https://www.qemu.org/docs/master/system/monitor.html>`_ to
stdin/stdout. Use ^P (not ^A) to switch to the monitor.
This starts Qemu emulator with a bunch of useful options, to run
the Liminix configuration you just built. It connects the Liminix
serial console and the `QEMU monitor

stdin/stdout.
You should now see Linux boot messages and after a few seconds be
presented with a login prompt. You can login on the console as
