I think we'd do better with this being a separate knob. I can envision=20
systems running at securelevel 2 that would both want and not want to be=20
able to add new devices. :-) Consider a system with disks on FC. Disks can=
come and go, but if high securelevel implies no-new-devices, you can't=20
really take advantage of that. I realize some systems may love that, but I=
believe others won't. :-)
As a separate knob, each installation gets to do things as it wants. :-)
