Reading the devfs faq was indeed a scare. It says that none of my
Linux systems is sufficiently up-to-date to run devfs, and I'd need
to do some brain surgery to get them that way. Or a new OS install
(RH 6.2 maybe) and spend some weeks recovering. NOT what I'd expect
most users to get right, and something I've found is best avoided.

At least in the 2.4 tree, until distros come out devfs-ready/enabled
AND (!) they're pretty widely adopted. The 2.2.14 backport seems to have
the 'usbdevfs' still working (if I apply some more patches :-) ... doesn't
seem right to need to redirect most developers to that release though.
Big changes like devfs need reasonable migration plans, and I don't
see how this one's supposed to work. The general rule of thumb is to
make sure people can use the "old" solution until the infrastructure
for the new one is fully deployed. I've seen folk start OS migrations
with broken plans (SunOS 4.0 anyone?) and it's been a big exercise in
pain and frustration for all parties.
