(and thanks, I >forgot that all of this is on IA-32) I will not change the disklabel format, so as such that will not change. It should be noted that a larger sectorsize can be used in the disklabel data, and thus it would be trivial to extend the life for disklabel a little bit. Geom will deal with all I/O requests as 64 bit byte offsets, so as such GEOM will solve the problem, and provided the disk-driver authors follow suit, this entire thing can be fixed before 5.0. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk@FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.
