    Subject[RESEND] [PATCH] nfsroot.txt (against Linux
    [This message was sent to the LKML on Mon, 6 Feb 2006 16:29:46 +0100
    and nobody replied. Perhaps you did not see it in the flood of mails.]

    Hello dear developers,

    I today booted the first time my embedded device using Linux,
    which was booted by pxelinux, which then bootet itself from the nfsroot.

    This went pretty fine, but when I was reading through
    Documentation/nfsroot.txt I saw that there are some more modern versions
    available of loading the kernel and passing parameters.

    So I added them and the patch for that is attached to this mail.



    P.S.: Please reply to nico-kernel2 //at//

    Latest release: ccollect-0.3.2 (
    Open Source nutures open minds and free, creative developers.
