Well, that would take one big disk :-)  Unix files can not span physical disk
partitions, at least on more common version of Unix. (Has anyone changed this?)
This pretty well limits the file size more than the kernel internals.

Then again, the largest file that I've seen in "real-life" is a 247mb kernel
core dump :-)
