Ok. I don't see that much of an issue as such installed stuff won't be upgraded by apt or OTA anyways. So not real need to keep it in the apt database I guess. > > if your package registers with the system anywhere (i.e. a new gstreamer > plugin that registers with the system gstreamer database) this will be > overwritten as well ...

Hmm ok... So it seems that in cases where you really just install a binary (e.g. copying it to /usr/bin/) this is actually a viable option and won't break on OTA updates? That's great to know. I was always worried that any modification in rw mode would very likely cause future OTA upgrades to fail and leave you with a broken system. Thanks for the explanations Oli!
