    Hey Karim,
       The installation has gone through smoothly and I have managed to get an
    linux-2.6.3 up and running with LTT.
    I checked the documentation and it says that I need to do an insmod on the
    tracer but I have compiled it as a part of the kernel. Now the documentation
    says that I should execute the createdev.sh to create the devices. When I
    execute that I get errors related to tracer. When I try to execute the
    tracedaemon I get that relayfs is not mounted. Can you please tell me how to
    go about doing the first part. After doing all this I want to run some test
    cases and see how does LTT generate traces. Later on I would also like to
    add rtai to this and see the traces from that too.

    Thanks!

    PS. I would like to write down a small howto on this and pass it on to you
    so that newbies like me can have a good ref. Thanks for the help.
