    This question is answered by the blfs book. First alsa-lib
    and after alsa-utils.

    No ! I am running a 2.6.32 kernel and never installed
    alsa-driver. Anyway if the sound system is something very
    exotic it might be necessary ...

    Humm ! I don't really understand this method. In my opinion
    if you want to have a custom distro you first install a
    basic systme on a partition or in a directory. Once the
    basic system is installed (more or less the content of the
    lfs book) you simply chroot to this new system to install
    the rest of the stuff. Following this scheme there will be
    no problem. I did it many times !

    It leads me to a more global question : you say you want to
    build a custom distro but do you have some kind of
    documentation to do that ? If you plan to do that on your
    own, it's a big deal ! Anyway I'll suggest you to have a
    look at the lfs book. It might be that the installation
    schedule suggested by the lfs team is not suitable for you
    but in my opinion it is better to check this point before
    "reinventing the weel" as we say in french !
