Install of Arch 2023-11-01 not building right

Following this post are the steps I am following to install Arch with btrfs on MBR/Bios install. doing a single partition setup. The ultimate goal is to get a manageable base system for a Panasonic cf52 toughbook. I joind the Arch forum and was met with basic rudeness. Not here to bash that community I know when I am not welcome. Anyhow my issue is that after the system is rebooted after arch-chroot and I unmount the system and reboot. Grub boots the system just fine from what I can tell. Once the system is booted and just before I log in I am asked to set locale and root password (this is not normal behavior for Arch). Then it asked me to log in. I do and I get the following prompt
-bash-5.2#

I have a limited set of tools to use and pacman is not one of them. my user account is not there and my fstab is empty. I check fstab prior to leaving arch-chroot and the file was there as it should.

This is my first attempt at btrfs and I am still not sure what i am doing wrong. It appears the file system is not mounting correctly or only partially. Hopefully I can get more help here than I did earlier. I am practicing this build on a vm before taking it to the laptop. I want to make sure my steps correct for what I am trying to do before going live.

I am not running this as a script. Its for copy and paste. I have done this to many times with failure and got tired of typing.
