Net_nfs4 has no build function

Question

Hello, I don't understood how can I build net_nfs4 hook for Diskless_System NFSv4
# sed s/nfsmount/mount.nfs4/ "$root/usr/lib/initcpio/hooks/net" | tee "$root/usr/lib/initcpio/hooks/net_nfs4"
after I copied from "$root/usr/lib/initcpio/hooks/{net,net_nfs4} to $root/usr/lib/initcpio/install/
after build from new mkinitcpio.conf kernel, and get this error.
==> ERROR: Hook /usr/lib/initcpio/install/net_nfs4 has no build function
And this on remote machine. What I did wrongly?

Did you look at the file you created? I'm no expert wrt initcpio, but from what I've seen only the files in initcpio/install have a build function.
