Hi bill. Are you suggesting that I should consider
changing the on-disk format of disklabel such that the size of a partition
is represented by an off_t, a 64-bit signed value? Do you think this might
be overkill since NetBSD seems to already address physical disk sectors as
unsigned 32-bit valuse, a state of affairs which will currently let us talk
to a 4-TB disk? I was merely thinking that the disk drivers and
disklabel(8) program ought to reflect that reality and print out meaningful
data. Is there a semantic I'm missing, and unintentionally changing?
Changing the on-disk format seems like quite a significant one, and
something to be worked toward, whereas I was mostly suggesting a cosmetic
change, initially, at least, which would improve the usability of NetBSD.
Please tell me if I'm missing something, because I certainly
want to do what's best for NetBSD as I strive to make it work well with
these huge data stores.
