I know personally I was thinking of removing the vfat and opt partitions and format/expand home to the whole eMMC. Then hopefully I can set it so that only the microSD card is exported over mass storage, as most of my data transfer will be via a Linux machine anyway so mostly I will not need mass storage support.

It is bad though that we have to do this. The partition scheme should have been better thought out. I am certainly thinking in the above scenario I may also symlink some stuff from root to home as well. I do not want to have to worry about root filling up.
