This is only a short question: Is it safe to use the "apt-get upgrade" command in Maemo 5 (PR1.2)? I've issued it and there are about 18 packages that need upgrade (many of them are Python related). I'm afraid of upgrading because Nokia's appmanager does not informs about those updated packages (it only upgrades them together with the corresponding apps) and I have read different opinions about using this command in Maemo (impossible future OTA updates, etc). Thank you.
