Hi Feye, The linux-yocto kernel has patches in it to enable booting via a userspace NFS server, which needs to use high port numbers for its mountd and nfsd daemons. You will need to include these patches in your custom kernel if you wish to continue using our userspace NFS boot method. Bruce, can you point Feye to this patchset?
