I've did some tests: The number of inode after a fresh install of
9.0-RC2 is half the number of inode after the fresh install of a 8.2.
I've install a 6Gio hard drive, MBR, no swap partition and all in /
(under VirtualBox).
9.0 has the dubious change of increasing the default block size in
newfs from 16K to 32K (and, correspondingly, increasing the default
fragment size from 2K to 4K). It is missing the corresponding change
of increasing the number of fragments per inode (NFPI) from 4 to 8.
That should be "reducing ... (NFPI) from 4 to 2".
Thus if you blindly accept the newfs defaults, you get half as many
inodes as before.
I forget to mention than newfs on a regular file to verify this is
quite broken. You now have to write a label to the regular file,
since the usual mechanisms for specifying the geometry when there
is no label (-S sector-size -s size or even -Tfoo) no longer work.
I want to use the usual mechanisms and not mess around with labels.
There are relatively minor documentation bugs related to this. -S,
-s and -T are still documented, but after removal of many geometry-
related options near -S, there are plural references to the single -S
option and other anachronisms related to geometry, which together
result in the description of -S being mostly wrong. Also, -s is
arguably a geometry option but it is not in the geometry section. The
geometry section with only -S in it makes -S unsorted relative to the
other -[AZ] options.
