First thing when I got home after work was update over WiFi. The N900 still had lots of battery left since I took it off the charger this morning, so I just started the update.
I had only 40 MB free on the rootfs but still gave it a try, and it worked flawlessly. Just be careful to avoid extras-devel like the plague and no problems should occur.
I have a sneak suspicion that apt-get dist-upgrade may have been a mistake on my part. Been running for at least 1hr now and I am running dangerously close to running out of space - had 69 free when I started.
Looks like a flash may be in my future.
Run 'apt-get clean'. Wipes all the downloaded .deb packages.
How can I update to PR1.1 without NSU(which removes some data) ? It gave me some message like "To update your device to this version of operating system you should use NSU" But I think I dont have to use NSU, do I? It seems like its related about my rootfs usage. How much free space does it need? I have 25~ megabytes.
