As pointed out already… kmod in Debian is already changed to having
libkmod in /usr instead of /lib¹. kmod is being maintained by Debian
developers who are also involved with Systemd.

Thus… /usr mounted later… all drivers in order to actually mount /usr
would have to be compiled into the kernel with that updated kmod package
already. And they just moved the library, not the binary for now.
Worrying themselves they may break to much by moving the binaries.

However so far, that is just one package I am aware of. Devuan could
have its own version of it. Likely not all Debian developers propagate
the usrmerge.

[1] Please move libkmod to /usr/lib
