So using your df output and the assumption that they are *partitions* and not separate flash memory...

Could it not be possible to delete the /home/user/MyDocs partition of 27GB and resize the /home partition to fill that space.. thus giving /opt the full 30+GB of available space for applications? Ext2/3 support resizing - I imagine since we're using symlinks at least / is ext2/3, what about /home? A small FAT partition could be used for the Camera (as I read that it won't work if a certain folder is ext2/3).

Also, symlinking /usr, /lib, and /var in the same way would also cause the rootfs to be virtually unused correct? It would be mostly a glorified boot partition with configuration files (/etc)? (Or mounting over existing /usr, /lib, and /var with the bind option to achieve the same effect?)

And for anybody wondering why the numbers don't add up to exactly 256MB or 32GB, it's because every filesystem type has overhead of it's own. When you format a drive in NTFS, FAT/32, Ext2, Ext3, etc - it uses a part of the space to store it's own information to know what all is going on with that partition. This is why the rootfs shows "227.9M" for example instead of 256.
