need to mount root fs in RAM
I've board with compact flash. I've put some library and other stuff in /cfroot folder. Now I need to boot this machine via PXE to pick up linux and initrd image from PXE server and it should mount /cfroot folder lying on compact flash as '/' in RAM.
I've setup PXE server and via NFS I'm able to boot as well. But rather than NFS how should I mount /cfroot as '/' at the time of boot so that NSF is not required at all.
This is for Ubuntu 7.1
