Primarily laziness:  I know procfs and it works well for me.

I don't think the TC stuff can do what I need.  However, there are
a lot less constraints on the text configuration interface, so I imagine
I can get sysfs to do what I need.

I was not aware that procfs was off limits.  Does sysfs exist in the
2.4 kernel?  (I'll also want to backport the redirect device code to
2.4, even if just for my own kernel builds.)
