The klibc nfsmount helper only supports NFSv2 and NFSv3, so it rejects LAVA's v4.2 mount option before reaching the server.

Extract mount.nfs from nfs-common while creating the initramfs, copy only its runtime dependency closure, and replace nfsmount with a compatibility wrapper that normalizes v4.x options. Keep the temporary helper and packages out of the final rootfs.
