+# Build the Dangerzone VM for running podman
+
+Thanks, [alpine-make-vm-image](https://github.com/alpinelinux/alpine-make-vm-image) project. License: MIT
+
+To build the VM image:
+
+```sh
+docker run \
+    --privileged --cap-add=ALL \
+    -v $(pwd):/build ubuntu:latest /build/build.sh
+```
+
+This will create a VM image file called `dangerzone.qcow2`.

+#!/bin/sh
+# vim: set ts=4:
+#---help---
+# Usage: alpine-make-vm-image [options] [--] <image> [<script> [<script-opts...>]]
+#
+# This script creates a bootable Alpine Linux disk image for virtual machines.
+# If running on Alpine system (detected by file /etc/alpine-release), then it
+# also installs needed packages on the host system. On other systems you must
+# install them yourself: qemu-img, qemu-nbd, and mkfs utility for the chosen
+# ROOTFS. If $APK is not available on the host system, then static apk-tools
+# specified by $APK_TOOLS_URI is downloaded and used.
+#
+# Note that it does not create any partitions (it's really not needed),
+# filesystem is created directly on the image.
+#
+# Arguments:
+#   <image>                               Path of disk image to use or create if not exists.
+#
+#   <script>                              Path of script to execute after installing base system in
+#                                         the mounted image and before umounting it.
+#
+#   <script-opts>                         Arguments to pass to the script.

+#      --keys-dir KEYS_DIR                Path of directory with Alpine keys to copy into the image.
+#                                         Default is /etc/apk/keys. If does not exist, keys for
