Howto create own archlinux distro

configure os

download latest archlinux cloud image:

wget https://linuximages.de/openstack/arch/arch-openstack-LATEST-image-bootstrap.qcow2

make sure we have libguestfs installed:

pacman -S libguestfs guestfs-tools

resize image:

cp arch-openstack-LATEST-image-bootstrap.qcow2 arch-openstack-LATEST-image-bootstrap_100G.qcow2
qemu-img resize arch-openstack-LATEST-image-bootstrap_100G.qcow2 +99G

expand image:

virt-resize --expand /dev/sda1 arch-openstack-LATEST-image-bootstrap.qcow2 arch-openstack-LATEST-image-bootstrap_100G.qcow2

change password:

virt-sysprep -a arch-openstack-LATEST-image-bootstrap_100G.qcow2 -q --root-password password:vidalinux

uninstall cloud-init:

virt-sysprep -a arch-openstack-LATEST-image-bootstrap_100G.qcow2 --run-command "pacman -R cloud-init --noconfirm"

on centos copy the image to this directory:

cd /var/lib/libvirt/images/

mount image:

qemu-nbd -c /dev/nbd0 arch-openstack-LATEST-image-bootstrap_100G.qcow2 
kpartx -a /dev/nbd0
mkdir /mnt/archlive
mount /dev/mapper/nbd0p1 /mnt/archlive
mount -o bind /dev /mnt/archlive/dev
mount -o bind /proc /mnt/archlive/proc

enter enviroment with arch-chroot:

arch-chroot /mnt/archlive

initialize the pacman keyring and populate signing keys:

pacman-key --init
pacman-key --populate archlinux

enable sshd service:

systemctl enable sshd 

configure hostname:

echo "archlive" > /etc/hostname
