- As far as I know, there is nothing to prevent you from partitioning the whole
- drive into one partition. In fact, the c partition is usually the whole
- disk. There is a unix limit, due mainly to the number of direct/indirect
- pointers (not to be confused with inodes), which is, I believe, about 4GB.
- This amount is higher than most practical requirements for max data block
- size. Please post any responses because I would like to know if I'm wrong.
