Perhaps it should be a second variable, eg: scsi_verbose..  and a =

corresponding sysctl  hw.scsi_verbose (or hw.scsi.verbose if there is =

potential for more hw.scsi.* variables).

Then, the code can do a 'scsi_verbose =3D bootverbose' once at first star=
tup =

time, and references to bootverbose can be changed to scsi_verbose in the=
 =

cam code.

At the moment this would pretty much have the same effect, but the prospe=
ct
of twiddling bootverbose itself on the fly at runtime sends a chill down =
my
spine.. =
