The group "operator" gatekeeps a few superuser abilities (dumping disks, manipulating tape drives -> means gid operator on device nodes). This group is also used with group-access bit on the setuid-root shutdown command (mode ug+x,u+s). Some people use this to shutdown/reboot their machines, but use of that group is giving them disk read access also, which is wrong. It would be a pain to re-gid all the device nodes, so instead let's renumber the operator execution gid into group "_shutdown". Users using this shutdown/reboot functionality will notice it no longer works, and move themselves to the correct group. Various choices discussed at large, this seems our best choice. ok sthen
