I posted the new kmod package here explicitly so that users can get this
package in preparation... I'll post it again since I changed the server
I'm hosting these on:

Currently, kmod is patched to respect config dirs in /usr/lib, but
modules in /lib. After removing the patch, it uniformly searches
/usr/lib for everything (I'm intentionally ignoring /etc and /run here).

As with any large change, I'll mention on dev-public when this goes to
testing, and there will be an associated news item when it moves to
core. I realize this is a harsh change, but I don't really have many
options for doing this more smoothly. If you're using the stock kernel,
this should all just work. mkinitcpio has supported this setup for
months now, and I've had my own kernel in /usr/lib/modules for almost as
Worst case scenario, users of custom kernels can:
- manually move /lib/modules/mycustomkernel to /usr/lib/modules/ until
they can do a proper rebuild.
- boot a stock -ARCH kernel (you DO have it listed as a fallback,
right?) until they can do a proper rebuild.
Emphasis on "until they can do a proper rebuild". It's important that
this all gets done before we introduce a new glibc package that wipes
out /lib entirely. If you have custom kernel bits lying around in
/lib/modules, it's going to block the eventual glibc upgrade that brings
this (no, it won't be immediately with 2.16).
