Based on the rhetoric udev is oriented toward implementing policy and uSDE, articulating policy. It seems to me that the code that should be run on device add and remove ought to be implementation oriented not policy oriented. When policy articulation is wanted it belongs in the user interface. This could be a set of files to build the final config file or a library and user interface. A bit like using EVMS to manage dm. Just my $0.02 in case distance lends perspective. I also wonder how one is supposed to pronounce uSDE, you-zdee, us-dee, us-day? -- ________________________________________________________________ J.W.
