    I would say depmod changed the API from /lib/modules to
    /usr/lib/modules. Re-assign?

    A right, the last upload of kmod changed to use:

    --with-module-directory=/usr/lib/modules

    Looping in Marco for comments.

    The problem is, this now ties linux, kernel-wedge and kmod together.
    And with backports and the implicit nature of dh_movetousr, this is not
    a good idea right now.

    So we need to
    - make /usr usage explicit (in linux-signed-* it is still completely
    disabled, because of this implicit usage)
    - teach kernel-wedge to not assume

    I can revert it if it causes too much trouble, but maybe this is just
    the right time to switch the kernel packages to /usr/lib/modules/ as well?

    We can't change this on our own. The usage of $BASE/lib/modules is
    baked in pretty deep into the kernel build.

    | MODLIB = $(INSTALL_MOD_PATH)/lib/modules/$(KERNELRELEASE)
    and
    | depmod -b "$INSTALL_MOD_PATH"

    depmod need to learn to work with MODLIB to even be able to change this
    value.

    The main linux build does not break, because we skip depmod during
    build. But any other, including manual linux builds, will break.

    Hi!

    This breaks compiling my own kernel with:

    time eatmydata make -j16 bindeb-pkg LOCALVERSION=-t14

    Likely going to downgrade and pin kmod to a working version as I am
    seriously fed up with usr-merge related bugs. (Yeah, it is called unstable
    for a reason and if I use it unstable is what I may get. But I really
    don't see how any possible benefit justifies that immense and error-prone effort. Anyway it is not me doing that work.)

    Best,

    Work-around:

    […]etc/apt/preferences.d% cat kmod
    Explanation: Bug #1063804: FTBFS: depmod: FATAL: could not search modules: No such file or directory
    Package: kmod libkmod2
    Pin: version *
    Pin-Priority: -30000

    Install kmod and libkmod2 31-1 from snapshot.debian.org.
