1.  If those geom modules do not reduce their providers to prevent
this metadata from being overwritten, they are buggy.

2.  Why not simply allow the -s argument to newfs to be negative so
    "-s -200" means "reserve 200 sectors" ?

Never attribute to malice what can adequately be explained by incompetence.
