AIX uses an unsigned short for inode number.  This would limit one to
65,535 inodes (2^16-1) except that, for some reason, mkfs only allows
signed positive inode numbers.  You might think this would allow 32767
(2^15-1) inodes, but mkfs further restricts the number to 32000.  News
B, at least, forces you to use a single file system for news through
its use of hard links, even when you are sure that there will be no
cross posting.  This makes it tough to keep a full feed.

Does anyone know if news C fixes this (I know, I know, wrong
group...)?

Not an official spokesman for IBM, and speaking for myself.
