Who came up with that nondescript subject line?
BTW Trevor, you need to fix your clock. As much as I would have loved it,
it's not yet June.
Sometime on Jun 12, Trevor Warren assembled some asciibets to say:

I can tell you that the maximum size of swap space (all swap partitions)
would depend on the size of your address bus. This is the same for your
RAM. Basically, your primary memory (Real | Virtual (not the or operator.
they are not added, but complement each other.)) must all be addressable
by the muP. If you have a 32 bit address bus, that means 4GB of primary
memory.
On the XT, with a 20 bit address bus, we could address 1MB.
The file system would have similar restrictions, but I don't know what
they are. The ext2 fs had a 2GB limit, but that has been overcome with
version 0.5a.
There is still a limit on the size of single files.
The inode structure limis the file size to about 17GB, but the address bus
limits it to 4GB. I think ext2 limits it to 2GB cause it uses only the
first 31 bits to address an offset into a file (negative offsets are
allowed in the setoffset call).
