Until someone that knows more than me posts, maybe this will help.?.?

That doesn't seem like the builder image. I can't remember the output of either one, but just glancing at your output. It loads the irda driver, which wouldn't be necessary on the builder image, and then tries to mount the file system. It shouldn't need to mount the file system at all until you load the player image back on. So my guess would be your upgrade utility isn't working properly.

On a side (but related) note, one thing that might help is, with the devel image installed, drop to a shell and run fdisk /dev/hda. Then erase every partition there and save it. That will make the drive apear to be empty. Then run the builder image. This will erase any doubt about the ntfs causing problems. You shouldn't have to do this, but if you are having problems it's good to try everything. If you have never used fdisk, this may be to technical and I wouldn't worry about it.
