Well, the on-disk MBR and NetBSD disklabel structure uses uint32_t
to store partition location and size as a LBA.  2^32 sectors
works out to 2TiB of storage.  So, the only issue is that signed
and unsigned quantities are being mixed in sysinst.  Fixing
that wouldn't solve the real issue though.

Easiest thing would probably be to use a smaller (under 1TiB) disk for
the system drive.  GPT could be used on non-boot drives.

This doesn't really help, but it should at least explain things.
