  • XZ support in kmod.udeb

    From Marco d'Itri@21:1/5 to All on Thu Aug 22 16:40:01 2024
    It has been suggested to me that, since our kernels nowadays are built
    with CONFIG_MODULE_COMPRESS_XZ=Y, there is no need to link kmod.udeb
    with libxz *as long as* we also do not use depmod or modinfo in d-i.

    So, does d-i actually use depmod or modinfo?
    And if it does not, can I just remove them altogether from kmod.udeb?

    (Please Cc me on replies.)

    Yes, it does. I think we should get rid of it however.

    depmod and modinfo are used by other udeb packages (partman, hw-detect...).

    depmod and modinfo are used by other udeb packages (partman, hw-detect...).

    All the depmod calls are not needed, as the kernel packages are the sole responsible ones.

    For modinfo, hw-detect tries to extract the description of the modules
    to give users a list for manual loading. Under what circumstances will
    udev not auto load the module, but manual loading will result in
    something working?

    There's potentially quite a lot of modules that aren't going to be
    triggered by udev, e.g. extra filesystems or hardware that's not
    discoverable.

    hw-detect only does this for network drivers.

    I do not see any postinst in kernel modules udebs. Am I missing something?

    All the depmod calls are not needed, as the kernel packages are the sole responsible ones.

    For modinfo, hw-detect tries to extract the description of the modules
    to give users a list for manual loading.

    FWIW, some time ago I submitted a patch for hw-detect which could use
    "modinfo -F firmware" as an additional way to find out which module must
    be reloaded after installing missing firmware.
