Note: I have worked with systems with multiple SCSI and EIDE buses and many
drives. And my main point is that there are main devices that do not need
the cryptic naming sceme as they limited by nature. (ex. EIDE devices,
serial ports, etc) And the main problem with the old naming sceme is with
devices that allow the connection of large numbers of other devices. Since
the problem is with these special cases then then change in the naming sceme
should be limited to these devices.

I like some of the concepts of dev_fs as well. Others I am currently
neutral about. I am not arguing against the dev_fs theorem itself just the
against the unnecessarily changes in the currently device naming sceme.
SCSI might need a change but EIDE, serial ports, etc do not.
