No, we don't; we let people configure certain obsolete bits out (a.out
support etc), but we keep it in the tree despite the indirection cost to
maintain multiple interfaces etc.
Right. WE ADD NEW SYSTEM CALLS. WE DO NOT EXTEND THE OLD ONES IN WAYS THAT
MIGHT BREAK OLD USERS.
Your point was exactly what?
Btw, where did that 2TB limit number come from? Afaik, it should be 16TB
for a 4kB filesystem, no?
Partition tables describe partitions in units of one sector.
2^(32+9) = 2T
To prevent integer overflow, we should use only 31 bits of a 32-bit integer.
2^(31+12) = 8T
There's _terrible_ hacks to really get to 16T.

IMHO, a simple solution is to use "Logical Volume Manager" instead of partition
manager: we create 64bit filesystem in a Logical Volume, not in a partition.
That doesn't solve anything, if you are not using a 64bit filesystem.
"partitioning is obsolete" ;-)
LVM is nothing but a partition manager...
