So, in my /home/user I have both the Ice Age 2 trailer which is in /home/user in the internal flash; and "Rise of the Cybermen" ...

it seems to be that you need Linux, which I do not have...

Then later, what we want is for the union as a whole to be mounted on /, and the old root filesystem to be one of the constituents of the union. So I'm curious about exactly how this is achieved, because my guess is that "mount -t unionfs -o dirs=/ unionfs /" would not work (because of recursion).
- /home/user
- /var/lib/install
- /var/lib/gconf
- /usr/share/themes
- /etc/others-menu
As you say, unionising / itself could lead to interesting effects (but I assume unionfs would not recurse into itself).
[Doctor Who]Really? And I'm using your preset encoder to watch series 1 again on the tube :-)
What line? I've not yet seen another 770 when I'm on the tube, so I'll keep an eye out ;-)
Cheers,

and as Andrew said - you can use 'cfdisk' from xterm on the 770 itself which is probably the quickest and most sensible solution.

This could be solved by mounting at a very early stage (as Knoppix does). However, especially with software updates from Nokia, this could cause more grief than what you'd gain from it, so I (I'm the one who wrote it) decided to suggest using it for subtrees of the root FS only.
