I wouldn't say you shouldn't be able to. (Outside that I think
Bluetooth is a pile of smelly carp, people shouldn't have to bend over
backwards to support, but that's a different issue...)

"design mistake" is a perfectly reasonable description, and I'd agree
with that. It's also not pejorative, but I'd say the two vocal sides
of the issue are far too polarized to notice that. "truck full of
manure" is probably a bit far, but that description only holds if
important things which shouldn't need a dependency on udev gain or
keep them. Rather like how installing a console Qt app on a Debian
server pulls in X.

Sure.

There's little use in explaining to someone why they should use
something apart from what they're comfortable with. Moving out of a
comfort zone requires personal motivation, not external. If udev works
for someone, they should use it. If they discover udev is getting in
their way, then they should look for alternatives.

I use apache2+squid3 on my server, despite hordes of people telling me
I should use nginx. Apache+squid works appropriately well for my
circumstance.

*That* is a matter of systemic complexity and maintenance difficulty;
the increased complexity tickles the spider senses of anyone who's had
to design, develop or maintain very complex systems with few
leave-alone black boxes. It's very difficult to increase the
complexity of a system without adding bugs or mistakes anywhere from
code to testing procedures to package management to end-user
maintenance. So when a system starts becoming more complex, and I'm
told that I'm going to have to go along for the ride, I get concerned.
Before Walt started pulling mdev from being a busybox-only component,
that was exactly the scenario. (Thank you, Walt!)

The only cases I've ever conceivably needed to use an initramfs have
been where I needed a kernel module available early. Rather than build
that as a module and build an initramfs, I simply build it into the
kernel. Certainly, there are portions of the kernel (particularly some
sound cards) where that doesn't work, and if someone needs those
portions available early, then an initramfs is going to be the tool
for them.

That's really not the reason for it. I mean, sure, I think the initial
reactions were mostly grumpiness and misinformed outrage, but I don't
think the contrariness really *baked* in until people got a twofer of
"you're going to use udev unless you write the code to get around it"
and "oh, you're writing the code? You're wasting your time and you're
going to fail." That, I think, is when the real malaise set in.

I concur.

For my part, I expect I'll use mdev in some circumstances, udev in
others. Right tool for the right job, and all that.
