Seamless Software Update
SSU is Nokia's new method for upgrading the tablets. Rather than requiring a reflash as with previous updates, SSU updates are pushed over-the-air and installed onto your live system. When Nokia pushes an update over SSU, you will see an update notification and be given the option to install the update—just like with your computer.
initfs and kernel
Generally speaking, SSU updates should be relatively pain-free, but there are a few issues to watch out for. If you have an aftermarket kernel or intifs installed (like the rotation support kernel or fanoush's bootmenu) and a kernel or initfs upgrade is pushed, they will be overwritten and you'll need to wait for your kernel or the bootmenu to be updated to reinstall them.
osso-software-version
If the update doesn't show up for you at all, you may have accidentally (or intentionally) uninstalled osso-software-version-rx*4, which is required to update. You can get it back by simply running an apt-get install osso-software-version-rx34, for the N800, and an apt-get install osso-software-version-rx44, for the N810. Then updating your repository list in Application manager.
