[SOLVED] Diskless booting.

Question

I am trying to create a diskless installation of arch using the wiki article Diskless System and I am failing miserably.
This is the section that is causing me trouble.
This works fine:
sed s/nfsmount/mount.nfs4/ "$root/usr/lib/initcpio/hooks/net" | tee "$root/usr/lib/initcpio/hooks/net_nfs4"
When I try the next command I get this:
cp "$root/usr/lib/initcpio/install/{net,net_nfs4}"
cp: missing destination file operand after '/srv/nfs/archlinux/kiosk/usr/lib/initcpio/install/{net,net_nfs4}'
Also this sentence is causing me quite a bit of confusion also:
"From the base mkinitcpio.conf, replace the nfsv3 module with nfsv4, replace net with net_nfs4, and add /usr/bin/mount.nfs4 to BINARIES."
If someone could please provide a little bit more detail about what I need to do there.
Thank you in advance for your help!

"From the base mkinitcpio.conf, replace the nfsv3 module with nfsv4, replace net with net_nfs4, and add /usr/bin/mount.nfs4 to BINARIES."
I wonder if the directions to 'replace' are just misleading. I'd try modifying mkinitcpio.conf as follows:
Put nfsv4 in the MODULES array.
Put net_nfs4 in the appropriate location in the HOOKS array. It probably needs to go in the same location the 'block' hook would normally go.
Put /usr/bin/mount.nfs4 in the BINARIES array.
I get the following:
# mkinitcpio -g $root/boot/initramfs-linux.img -k $root/boot/vmlinuz-linux -c $root/etc/mkinitcpio.conf
==> Starting build: 3.11.6-1-ARCH
-> Running build hook: [base]
-> Running build hook: [udev]
==> ERROR: Hook 'net_nsf4' cannot be found

==> Creating gzip initcpio image: /srv/nfs/archlinux/kiosk/arch/boot/initramfs-linux.img
==> WARNING: errors were encountered during the build. The image may not be complete.
The file(s) exist in both /usr/lib/initcpio/hooks and /usr/lib/initcpio/install.
However the system does boot with the "net" hook.
