Any changes you make will not survive a reboot. If you think it likely you will want to edit a file, then either include the parent directory in bind-dirs rather than the file, or perform the file operation on the file in /rw/bind-dirs.

You can add persistent rules to `/etc/hosts` file using script `/rw/config/rc.local` that is designed to override configuration in /etc, starting services and etc. For example, to make software inside some TemplateBasedVM resolving the domain `example.com` as `127.0.0.1` open `/rw/config/rc.local` inside this TemplateBasedVM and add:
~~~
echo '127.0.0.1 example.com' >> /etc/hosts
~~~
After every boot of the TemplateBasedVM `rc.local` script will add line `127.0.0.1 example.com` to `/etc/hosts` file and the software inside the TemplateBasedVM will resolve domain `example.com` accordingly. You cam add several rules to `/etc/hosts` the same way.
