Kernel options to boot root over NFS (kernel-4.1.fc22/linux-4.1.3-200.fc22.x86_64)

[Nestor Waldyd]

Hello,
I would like to compile a kernel bzImage in order to boot root over NFS. I am using the fedora kernel source package (kernel-4.1.fc22/linux-4.1.3-200.fc22.x86_64). What kernel options should i modify in Kernel Configuration in order to do so? (I have already configured both tftp and dhcp server, and PXELINUX)
Best Regards,
Nestor Waldyd
