[dM: I think one problem with this is that the information cannot _not_ be
[dM: there in the disklabel, so there is no way to have disklabel fall back
[dM: on its default algorithm.

I think that was my point.  I go nuts when I specify 16CPG or 32CPG
and let it do its thing and put it on the disklabel, and then when I go
back and remake the filesystem and --oops-- forget to specify cpg, newfs
ignores the values on the disklabel.

[dM: Unless you want to hijack some magic value (0 maybe, which is otherwise
[dM: nonsense as a cpg value) as meaning "let newfs try to be smart".

...which newfs should stuff there by default if it made the filesystem
with zero guidance.
