I guess my vision is even more limited than you think; I must confess that I don't understand your comment at all. What does first-world have to do with anything?

The point is that the thing we think of as the "kernel" increasingly involves a layer of surrounding software which mediates between the kernel and the rest of user space.

I think that this poster is referring to the embedded problem. for embedded systems udev is
not an admantage, it's something to remove. currently they can get along just fine with an
old-stule /dev/directlry (populated only with the devices that actually exist)

as long as these things are kept optional I don't see this as a big problem (although the
authors of these tools do tend to forget that not every system is going to use them)

In my mind the bigger problem is that these tools are a middle ground between the kernel and
userspace, sometimes they are tied to one and sometimes to the other. this can cause surprises
when upgrading, and it's all to easy to get into a bind where you can't upgrade one piece
without having to upgrade a lot more, or where once you upgrade you can't go back.

Huh?

Indeed, the Openmoko guys found tat removing udev and prepopulating /dev saved them over 5s of
boot time - something very desirable in a cellphone!

Huh?

Doesn't OpenMoko take about 1.5 minutes to boot up?
