Comment 27 for bug 941874

Sorry if I'm using the wrong terminology, I just called it hooks because that is what the folder is named.

I mean I have added a script very similar to:

    /usr/share/initramfs-tools/hooks/dmraid

which copies the necessary kpartx files to the initramfs as well, when doing update-initramfs -u (at least that is what I assume happens ;)).

I include these for kpartx:
    /sbin/kpartx
    /lib/udev/kpartx_id
    /lib/udev/dmsetup_env
    /lib/udev/rules.d/95-kpartx.rules
