- No, 4 Gig; think of identification of indirect blocks for a total of two
- levels of indirection using a 24 bit value.

- Get around the problem:
-
- 1) Multiple partitions not exceeding the 4 Gig limit.
- 2) Larger terminal blocks.
- 3) Additional indirection levels.
- 4) Assumption of larger files = log-structure file systems (ala Sprite).
-
- I don't think it will be an issue that soon anyway.
