This is how I once did something similar to that wiki page using just an uninstalled Parabola iso file, it resulted in a bootable system. But watch out for weird stuff (mis)using installer images, they often have extra packages and scripts, and Parabola had some incorrect file permissions as noted in the code box. Hopefully I didn't miss out any steps when I wrote these notes . 
I installed Artix normally from a USB so don't have a guide for that.
$ sudo mount -o loop ~/Downloads/parabola-openrc-2017.09.30-dual.iso /media/squashfs/
$ cp /media/squashfs/parabola/i686/root-image.fs.sfs ~/test
$ sudo umount /media/squashfs
Wipe and format the partition to install on:
$ sudo mkfs.btrfs -f /dev/sdaX
Make a note of the UUID, need this for the fstab later although blkid will tell you.
$ sudo mount -t btrfs /dev/sdaX /mnt
$ sudo su
# unsquashfs -d /mnt/sq/ /home/me/test/root-image.fs.sfs
# exit
Other liveCD's I've tried unpack the filesystem, but a further step was required for the Parabola dual iso. Mount root-image.fs and copy the contents out.
$ sudo mount -o loop /mnt/sq/root-image.fs /media/squashfs/
$ ls /media/squashfs/
bin boot dev etc home lib lost+found mnt opt proc root run sbin srv sys tmp usr var
$ sudo cp -a /media/squashfs/* /mnt
$ sudo umount /media/squashfs
At some point the root-image.fs can be deleted, but it can be kept around for a while in case another attempt is required.
--: $ sudo rm -R /mnt/sq
fstab is an empty file here, create / edit fstab.
Security note: there are many directories and files that have the wrong group and owner, they should be root.
This image is intended as an installer CD, not a regular installation. One liner to fix this: (grep -v works the same as ag -v)
$ sudo chown root:root `sudo find /mnt -user $USER | ag -v "home/parabola"`
CHROOT TO PARABOLA:
$ sudo su
# for d in dev sys run proc; do mount --bind /$d /mnt/$d; done
# chroot /mnt
# pacman -Q>/Q.txt - create original package list - sudo is installed.
# /usr/sbin/useradd --create-home --groups wheel,rfkill,network,audio,optical,floppy,power $USER
# visudo -f /etc/sudoers.d/my_sudo
<yourusername> ALL=(ALL) ALL
# /usr/sbin/userdel -r parabola
# /bin/passwd me
# passwd -S root
root NP 09/19/2010 -1 -1 -1 -1
# passwd -dl root
passwd: password expiry information changed.
# passwd -S root
root L 09/19/2010 -1 -1 -1 -1
(Don't lock the root account unless sudo is installed)
/etc/locale ??????
LANG=en_US.UTF-8 - That was OK for me
# echo somename >/etc/hostname
# mv /etc/localtime /etc/localtime.utc.orig
# ln -sf /usr/share/zoneinfo/GB /etc/localtime
Edit /etc/hosts:
127.0.0.1 localhost.localdomain localhost somename
::1 localhost.localdomain localhost somename
There is no /boot/vmlinuz* so mkinitcpio won't work.
Download and install a Parabola kernel package manually from a mirror repo, it should have /boot/vmlinuz in it.
# pacman -U /somewhere/linux-libre-pae-4.15.17_gnu-1-i686.pkg.tar.xz
# exit
# for d in dev sys run proc; do umount /mnt/$d; done
# exit
$ sudo umount /mnt
Run update-grub in the existing Linux OS on the other partition
$ sudo update-grub
It created an Arch menu entry in /boot/grub/grub.cfg.
