Hi, An interesting problem with NFS on FC4. I built a vanilla kernel 2.6.15.6 with NFS options all set to 'y', then after compilation NFS functions are all statically built into kernel, not as loadable modules. But after I reboot the machine and boots up with new kernel, the NFS function fails whining can not locate sunrpc module!! It sucks since sunrpc is already statically built-into kernel! I tried to mount NFS share on this nfs server from on itself, but the mount operations all failed, though rpc.mountd authenticated without problems. Any one know why?
