Comment:
Actually, I think this should better be done by the package `i2c-tools`, which is  a dependency, as done in Debian and others, see e.g.
```
i2c-tools (3.0.2-4) unstable; urgency=low

  * Add ${misc:Depends} to all binaries.
  * Create an i2c group on install, and add a udev file to set the group
    and the mode of /dev/i2c-* nodes.

```
I can do that later.
