I was the first reply. None of this was trolling, it was legitimate gripes.

Please tell me exactly what I'm looking for, becuase I couldn't find
it. I read through your first email, and not once was the following

Fine, take the linker and move it to /usr/lib (Doesn't this require
patching the kernel?). But that wasn't the point of my typing here,
and you seemed to get stuck on that.
But you can truely tell me, with a straight face, the following things
belong in /usr/lib, let alone /lib? My whole point of this "troll" was
to point out we're spending time and pain moving from bad location A
to bad location B- shouldn't we just take a step back, stop following
Fedora blindly, and point out that some of this makes no sense at all?
* Kernel modules- these are "libraries" only in the strictest sense,
but even systesm sharing a common /usr have no need to share kernel
modules (or might be able to, if they are booting from different
kernels). So, proposed location- /kernel/modules.
* Kernel firmware- architecture agnostic. Most of this doesn't belong
in a library directory as it isn't executable code per se by the OS
itself; it is also architecture agnostic. Proposed location-
* Udev rules- once again, this is architecture agnostic, not
executable, etc. Why is this in lib?
* /lib/depmod.d/search.conf is owned by kmod 5-4- WTF is this, besides
a funny joke? Configuration in /lib?
* /lib/device-mapper/, /lib/multipath/, /lib/security/- no problems at
all with moving, this is exactly the type of move I do agree with, as
it is a logical separation that makes no sense.

/lib is one directory, as is /usr. That honestly doesn't seem like all
that much of a hassle to me. Ideal? No. But I'm not sure where the
"littering" of non-standard dirs in '/' comes into place.
Am I completely serious about the creation of a new /kernel directory?
Not really, especially as there seems to be an allergy toward
top-level directory creation (unless their name is /run). But hell,
throw it in /boot then! No new directory created. My point was, I just
don't see how having kernel modules, firmware, etc. in /usr/lib makes
any sense whatsoever.

Well when you're telling people in a follow-up email "Contributions
welcome. Especially in the form of rebuilds ;-)", somehow I felt like
commenting on the implementation wasn't off-limits...
