    I thought --ignore-install was completely broken, but no, because without it, the output contains *more* "install" lines:
    What you are actually seeing is that --ignore-install is applied only to
    the nfs module (the one which you have requested to load) but not to its
    own dependencies:

    diff -U 0 <(modprobe --all --set-version="6.0.0-1-amd64" --ignore-install --quiet --show-depends nfs) <(modprobe --all --set-version="6.0.0-1-amd64" --quiet --show-depends nfs)

    I am not sure if this is a bug or a feature, so this should be discussed
    with the upstream maintainer.

    So the possible solutions are:
    - the semantics of --ignore-install are changed upstream (this may take
    some time)
    - initramfs-tools learns to parse the install directives
    - nfs-kernel-server uses a different design

    No matter what happens to --ignore-install I suggest that
    nfs-kernel-server will replace the modprobe configuration with some udev
    rules like this one (untested):

    ACTION=="add", SUBSYSTEM=="module", KERNEL=="sunrpc", \
    RUN+="/sbin/sysctl -q --pattern sunrpc --system"

    nfs-kernel-server, for example, the 'install' command wants to invoke sysctl --pattern, but the busybox sysctl installed in the initramfs by default doesn't support --pattern. So the package would need to force initramfs to include the /sbin/sysctl from procps, and maybe also any pertinent files from /etc/sysctl.d.

    Looks like this is a different problem.

    FYI: I reported this one as #1024082, looks like the new /lib/modprobe.d/50-nfs.conf file is causing quite some problems.

    (FTR, this showed up at the Grml live system, see e.g. https://github.com/grml/grml/issues/193 )

    At this point we have established that for good or for worse kmod is
    behaving as documented, so we are down to one of:

    - initramfs-tools learns to parse the install directives
    - nfs-kernel-server uses udev rules instead

    I recommend the second option, which is much more general and robust.
