Hello,

could someone point me to the correct place in the source tree to hard code
the boot arguments for the kernel. I'm currently using the .config file to
pass the arguments in but they don't make it to the kernel. Then the kernel
dies mounting the root file system that isn't specified. So I'd like a
quick hack point to test if this is going to work at all. My ramdisk image
is working with 2.2 kernels so I think it should be ok to use for 2.4.

Thanks,
John
