Hello Aravinda,
I have two questions, could you answer me ?
First, what problems do you have about the current format of makedumpfile.conf ?
Second, what benefits do you expect from using SIAL ? I can't imagine
specific benefits with using SIAL now.
By the way, could you add kexec-ML to CC field from next time ?

Thanks
