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?

AFAIK, NFS client support needs to be selected as built-in during
configuration.
Rest is through kernel command line parameters.

There is a good description in 'Documentation/filesystems/nfs/nfsroot.txt'
