    Tom,

    Yes, well a cut down version of the kernel module anyway. Its in the
    attached tar ball. The kernel module requires pagg as well as relayfs
    to work. Basically the module tracks kernel events - in this case
    process execs.

    I've tested it on 2.6.10 with the pagg and relayfs patches from

    http://www.opersys.com/ftp/pub/relayfs/patch-relayfs-2.6.10-050113

    and

    ftp://oss.sgi.com/projects/pagg/download/linux-2.6.10-pagg.patch-4

    read() gives me a zero still once about a page of data has been read.

    Many thanks,
    --
