# pacman –S tftp-hpa

# cp /usr/lib/systemd/system/tftpd.service /etc/systemd/system

# nano /etc/systemd/system/tftpd.service

[Unit] Description=hpa's original TFTP daemon [Service] ExecStart=/usr/sbin/in.tftpd -s /srv/arch/boot StandardInput=socket StandardOutput=inherit StandardError=journal

Run tftpd

# systemctl start tftpd.socket

Enable to run at boot time:

# systemctl enable tftpd.socket

Created symlink from /etc/systemd/system/sockets.target.wants/tftpd.socket to /usr/lib/systemd/system/tftpd.socket.

# pacman –S nfs-utils

# nano /etc/exports

/srv       *(rw,fsid=0,no_root_squash,no_subtree_check) /srv/arch  *(rw,no_root_squash,no_subtree_check)

# mkdir /srv/arch

# sudo systemctl start nfs-idmapd.service           

# sudo systemctl start nfs-mountd.service

Client installation

# pacman –S btrfs.progs

# truncate -s 1G /srv/arch.img

# mkfs.btrfs /srv/arch.img

# export root=/srv/arch

# mkdir -p "$root"

# mount -o loop,discard,compress=lzo /srv/arch.img "$root"

# pacman –S devtools arch-install-scripts

# pacstrap -d "$root" base mkinitcpio-nfs-utils nfs-utils

# sed s/nfsmount/mount.nfs4/ "$root/usr/lib/initcpio/hooks/net" > "$root/usr/lib/initcpio/hooks/net_nfs4"

# cp $root/usr/lib/initcpio/install/net{,_nfs4}

Edit $root/etc/mkinitcpio.conf and add nfsv4 to MODULES, net_nfs4 to HOOKS, and /usr/bin/mount.nfs4 to BINARIES.

# nano /srv/arch/etc/mkinitcpio.conf

Next, we chroot our installation and run mkinitcpio:

# arch-chroot "$root" mkinitcpio -p linux

Client configuration

# pacman --root "$root" --dbpath "$root/var/lib/pacman" -S grub

Create a grub prefix on the target installation for both architectures using grub-mknetdir.

# arch-chroot "$root" grub-mknetdir --net-directory=/boot --subdir=grub

# nano "$root/boot/grub/grub.cfg"
