Does the attached diff take care of this appropriately? It inverts the
default for PC98 sysinstalls, and updates the helpful. It does not change
the newfs(8) default, under the assumption that (in general), you'll be
creating non-root file systems with newfs(8) and will therefore want the
new layout.
Do we know if anyone currently owns the task of adapting the PC98 boot
code to support UFS2? I would have thought (foolish me) that it would
fall pretty naturally out of the i386 support, but perhaps not...
