(I am the first guest) I used the /mnt/card to install on but I still go over the size, all kinds of things stop working when you have this. Even rebooting the machine will give you a host of errors. The partition needs to be much, much bigger for root. I\'ve not installed the latest rom, I\'m waiting for it to stabilise a little first, as I want to know how large I really need to have my root partition, 50mb is not enough, even symlinks take space.
