I'm not sure. I thought there was still a 2GB limit for ext2, but I'm
looking at fs/ext2/file.c in the 2.4.0-test9 kernel and it appears
that the limit depends upon the block size. I haven't looked at it
closely enough yet to puzzle out the relationship though.

I found this recently while poking around...

It gets around the 2GB limit for 32 bit systems by creating
multiple files exactly as you suggest.
