Have you managed to get stuff to install on hda2? Is there some trick
to it? When I try to upload an upgrade I've made containing an ext2
image as CHUNK_PUMPHDA2, it goes funny. The player just re-starts part
of the way through the upgrade sequence and then gets understandably
confused as it sees the hda2 image data as serial commands.

If I use CHUNK_PUMPHDA5 instead, it works.
