Comment:
In the headscale setup instructions, this directory is not created with any permissions that would allow writing by the headscale-specific user. Instead, they do a simple `mkdir -p /etc/headscale` call as root, creating a directory where other users and groups cannot write. This line should be removed, and replaced by a `mkdir` call in `post_install()`.

A conf file should be placed in `/etc/headscale` in `post_install()`, either containing the sample conf or a comment telling the user to look at `/usr/share/examples/headscale/config.yaml`. Either way keep the vsconf line.
The conf file should be listed in `conf_files`, refer to the manual.
