Qubes specific VM config files
==============================

Those files are placed in /rw, which survives VM restart, so can be used to customize single VM (not all VMs based on the same template).

-   `/rw/config/rc.local` - script run at VM startup. Good place to change some service settings, replace config files with its copy stored in /rw/config etc. Example usage:

    ``` {.wiki}
    # Store bluetooth keys in /rw to keep them across VM restarts
    rm -rf /var/lib/bluetooth 
    ln -s /rw/config/var-lib-bluetooth /var/lib/bluetooth
    ```

-   `/rw/config/qubes-ip-change-hook` - script run in NetVM after external IP change (or connection to the network)
-   `/rw/config/qubes-firewall-user-script` - script run in ProxyVM after firewall update. Good place to write own custom firewall rules

Note that scripts need to be executable (chmod +x) to be used.
