Or, on redhat, you could call it "kudzu". (Type "man kudzu".) I first
noticed it in the boot sequence during... 6.2? Might have been there

Now true hotplug is a seperate issue. Kudzu runs at boot time (or when you
type it in from the command line) and detects network cards and mice and
stuff. You can't hotplug PCI. (Well, you can, but not if you expect it to
WORK. Or if you don't want to replace burned out pieces of hardware.)
Generally, for hotpluggable bus types, we have a daemon. There's one for
pcmcia/cardbus devices, for example. I'm guessing there's something for USB
(I don't use it). All of this is sort of getting not-exactly integrated into
devfs, which also has a userspace daemon and does automatic device detection.

Auto-detecting oddball peripherals connected to serial and paralell ports
(mice and printers) is a problem for things like XFree86 or the print spooler
that actually uses them. (And if you run kudzu it'll get those too, it just
doesn't know WHEN to run because they don't generate a hotplug interrupt when
they get changed.) Again, a user space issue.

As for downloading fresh drivers newer than your distribution (ala debian's
apt-get), that's tangled up in binary compatability issues between module
versions. Installing modules for just about every single supported driver
takes up... ("du /lib/modules/2.4.2-2"...) 22 megabytes. I have PDF files
larger than that. (If you want to start a binary module compatability
flamewar, feel free, but it's an ooooooooold issue steeped in politics.)

As for replacing the entire kernel without the user prompting... That's just
plain dangerous. (Especially aimed at users who dunno what to do when things
go wrong. And I'm not just talking about 2.4.11...)

Such as the fact it's pretty much already been implemented by distribution
vendors, and is not really a kernel issue at all but a user space issue?

Have you tried Red Hat 7.2, with the KDE desktop? My cat HAS tried to use
it. (Sphynx sent an email I wasn't finished typing. Sat right in my lap,
reached out and pressed the mouse button. Kind of impolite, I thought. Then
again she's a lap cat, which means my laptop and her body compete for the
same ecological niche...)

There's an old saying on usenet. If you want answers, don't ask questions.
Post errors. It works for me.
