I think you misunderstand the comment. It has nothing to do with desktop or server software.
Rather, important functionality is increasingly required from user-space (not linked into the
kernel) daemons that run at the system level.

 But it has to do with desktop/server deployments. Embedded systems with 
a fixed set of hardware can often still be built with all the drivers 
built-in, a fixed /dev containing the correct nodes, and no need for 
early userspace or udev or probably most of the daemons you had in mind.     
There is plenty that can be done with a bare kernel and a minimal 
userpsace to push config. into it, just not in the desktop space.

Well at somepoint it's going to be cheaper to just run udev than mapping everything on your
own, even in embedded.

On my embedded systems, which are busybox-based, I use mdev instead.  Same basic idea though.

Isn't it fair to assume the desktop space by default and make it explicit if you're talking
about embedded Linux?
