Absolutely.  Also avoids the problem of new kernel devices being added
that then slip through, and the corresponding updates to all existing
namespace files.

Did you consider implementing this with two commands (e.g.  'drop' and
'permit') on the /dev/drivers file itself?  That would make it just as
easy to do this kind of stuff from a script/program without having to
craft a namespace file.

Obviously you'd have to have the #c device available until you're
finished "dropping" and "permitting" things, but perhaps that's not
really a problem.

Just some thoughts.
