My first question about Julian's devfs was how it lasted across
reboots (and the answer was an rc answer at the time).  I think it
again points toward a second boot file that stores configuration
- after all, in addition to devfs you want to store away which
drivers to lkm in - they are coupled.

This is (IMHO) flatly a requirement on devfs.  It has to work the
same way as it does now as well as any new way.
