The following is a template that I use to quickly setup a fresh install of Alpine Linux. Later on, it will be used as the basis for an unattended install of Alpine Linux.

1. Start out by creating a new file called myconf.sh on your workstation.
2. Fill it with the following shell script, review it, and modify it accordingly.
3. Boot up the Alpine Linux CD/ISO.
4. Run 'setup-disk' and reboot into the newly installed system.
5. Get this file onto the new system (e.g. by local networking or a USB stick).
6. As root, do: chmod +x myconf.sh && ./myconf.sh
7. Stick around for prompts.
