I use -mm and I'm complaining.

Knowing it's coming isn't the same as agreeing with it. :)

Once devfs is out, it's out for good. It is for all intents and purposes
impossible to maintain such a thing outside of mainline. You should know
that, udev's kernel infrastructure was developed pretty much entirely
within mainline and look how long it took to get even the present number
of drivers working with it.

It's pretty hard to put effort into devfs when said patches won't get
merged because it has already been decided by certain people that devfs
is not the way to go. For example the quick death without comment of the
earlier devfs-on-top-of-tmpfs patches.

Or, look at how hard of a time udev had gaining mindshare, how long it
was around for until now. Only shock tactics like marking devfs OBSOLETE
(at a time when udev was completely unready to replace devfs, making
it far from obsolete) got people switching.

It breaks a lot of my embedded setups which have read-only storage only
and thus need /dev on devfs or tmpfs. With early-userspace-udev-on-tmpfs
being - in my experience - still unready. Not to mention the general
bother of having to change dozens of desktop/server systems to work with
udev, but I doubt you care about that.
