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
configure /etc/hosts:
cat > /etc/hosts << EOF 127.0.0.1 localhost 10.44.1.44 archlive EOF

enable sshd service:
systemctl enable sshd
configure hostname:
echo "archlive" > /etc/hostname
configure timezone:
ln -s /usr/share/zoneinfo/America/Puerto_Rico /etc/localtime
stop and disable systemd-resolved:
systemctl disable systemd-resolved
nameserver configuration:
rm /etc/resolv.conf echo "nameserver 4.2.2.1" > /etc/resolv.conf echo "nameserver 4.2.2.2" >> /etc/resolv.conf

umount qcow2 image:
umount /mnt/archlive/proc umount /mnt/archlive/dev umount /mnt/archlive nbd-client -d /dev/nbd0 dmsetup remove /dev/mapper/nbd0p1
enable chaotic repo
install chaotic repo:
