Jesus, how many testing and devel non-optified apps did you install?

There is no (easy) way to increase root space. All methods require partitioning right now. I'm considering it but I have no idea how the firmware update is going mess with it so I figure I'll wait to here what happens to those that have changed their partitions around.

The default stuff in root comes from the operating systems. Then certain apps in extras install to root (bad behavior) like Evernote and OpenSSH. Some applications in testing and devel will install to root (though they really should be optified before they get into extras).
