dumpfs will obviously show information that might be changing, but
the geometry information is static, so that's ok.

tunefs won't work because it just manipulates on-disk data, it
doesn't tell the filesystem about it. Some values you can change
and activating them at the next mount. Some values you can only
change while unmounted, because the living filesystem overwrites
them.
