as johnpad mentioned, the update may fail and lead to an endless reboot if rotation is installed. if so, does uninstalling the rotation ensure a "seamless" update? i think many users like me just want to be reassured about this before going for the update..

I'm not aware of any evidence to support that. AFAIK, all existing rotation packages prevent the update from starting in the first place. The main culprit for reboot loops seems to be the preinstalled documentation and media.

But the point is that most users don't anticipate and don't clone to SD (users don't always have a SD or have space on the SD anyway).

With other systems (e.g. Debian), this isn't needed: boot messages are output to the screen, so that one can see what's going on and possible errors. This is not always convenient, but still much better than having nothing at all like on the tablet. Moreover, one can enter single-user mode from the firmware, so that one can try to fix things.

Sounds really interesting. Any more information, please?

No, this needs to anticipate. One should really be able to diagnose the failure without anticipating and without having a spare SD. This isn't much a problem for this failure as it occurs for many users, so that some of them can diagnose it. But some other uncommon failures could really be hard to diagnose.

Something is different on the tablet of every user for whom it's failed. No-one's going to be able to pin down what's common if what's been done to them isn't clear.

"Specific causes" meant - if it's failed for you - what, exactly have you done to the tablet since you last reflashed it? Saying "nothing, it's the same" and then later it turns out "well, I installed sliderotate" (not mentioning any particular user, here) means something was done.

Software doesn't fail randomly, unless there's a hardware failure. Something is different which is causing reboot loops etc.

I had the same problem. I had .documents linked to a folder on the internal mmc card, and the update process kept failing. The log read: mv: cannot rename '/usr/share/pre-installed/MyDocs/.documents/*': No such file or directory

After creating a new folder .documents under /usr/share/pre-installed/MyDocs with some dummy file in it, I could finally install the update successfully.

Some users said that the SSU broke their bootmenu, so how would this solve anything concerning the endless reboot loop?

Moreover this wiki page doesn't mention the tools to get USB networking before the reboot (http://wiki.maemo.org/USB_networking is silent on this point too).

Unfortunately not everyone remembers everything what they did since the last reflash, including things not done as root (as the SSU behavior also depends on user space, as it was shown).

I cannot understand why SSU installs anything to user's home directory at all. Home directory is for user to do anything he wants and trying to make a deb which works there 100% is not a easy task.
