After reading begriffs "[Tips for stable and portable software]", the
"Begriffs Buildfarm?" section caught my attention, as this is something I would
be interested in.

After emailing the author, a [public thread] began on the subject.

As we discussed how it could be done, I decided to experiment with the idea of
automating the setup of virtual environments with QEMU.

This screencast is a simple demo of automating the installation of
Alpine Linux 3.12.3 standard x86_64 with AutoQEMU[^AutoQEMU], which is nothing
more than POSIX sh, [expect] scripts and Makefiles glued together.

[^AutoQEMU]: The solution was a little too brittle to scale, and some
distributions proved to be particularly problematic.  I've [archived] my
progress if you're interested in what I've done, and maybe wish to continue.

As of this writing, I just worked on it for 2~3 days, so everything is still
pretty ad-hoc.

The commands from the screencast were[^script-command]:

[^script-command]: Only now, writing again what I ran on the screencast I thought that I should have tried something like [script](https://www.man7.org/linux/man-pages/man1/script.1.html). Maybe next time (thanks [klaatu](https://gnuworldorder.info/) for the tip!).

```shell
pushd `mktemp -d`
git clone https://euandreh.xyz/autoqemu.git .
make
make install PREFIX=$HOME/.local
autoqemu ssh alpine
```

It assumes that `$HOME/.local/bin` is in `$PATH`.
