Chromium OS building - Chromebooks

After building Chromium OS kernel 4.14.96 & my inability to figure out how to properly deploy it as an update to an existing Chromium OS installation like Arnoldthebat v72 (with Chrome OS Kernel 4.14.83)
efforts here -
https://forum.xda-developers.com/showpost.php?p=78830818&postcount=3
I will post here my efforts at building the full Chromium OS with the latest available Kernel - I will try & start with same version as arnoldthebat i.e. v72 which has now reached stable...
There will be a lot of editing here, as it's a learning curve to me...
First is to clone the Google Chrome OS repo -
I was given this link to learn how to do this -
https://chromium.googlesource.com/chromiumos/docs/+/master/developer_guide.md
As for building Kernel for ATB v72 - I will be keeping a log of instructions here...
I do the work from within a Ubuntu xenial 16.04.xx box as suggested by the documentation,
Preparation instructions:
Create a folder where the code will be stored (they suggest chromeos) I used code
from an ext4 partition/disk with plenty of space (mine 150 GB+)
$ mkdir code
input instructions to get to clone the repo later to reach here:
$ sudo apt-get install repo
$ sudo apt-get install git-core gitk git-gui curl lvm2 thin-provisioning-tools \
python-pkg-resources python-virtualenv python-oauth2client
Install depot_tools
$ git config --global user.name "John Doe"
$ git config --global user.email "[email protected]"
$ git config --global core.autocrlf false
$ git config --global core.filemode false
$ # and for fun!
$ git config --global color.ui true
Tweak your sudoers configuration
cd /tmp
cat > ./sudo_editor <<EOF
#!/bin/sh
echo Defaults \!tty_tickets > \$1 # Entering your password in one shell affects all shells
echo Defaults timestamp_timeout=180 >> \$1 # Time between re-requesting your password, in minutes
EOF
chmod +x ./sudo_editor
sudo EDITOR=./sudo_editor visudo -f /etc/sudoers.d/relax_requirements
Configure git
git config --global user.email "[email protected]"
git config --global user.name "Your Name"
Verify that your default file permissions (umask) setting is correct
put the following line into your ~/.bashrc
umask 022
preparation for enough disk space
in folder code/
sudo dd if=/dev/zero of=swapfile bs=1024 count=$((1024*3000))
mkswap swapfile
sudo swapon swapfile
git config --global http.sslVerify false
git config --global http.postBuffer 1048576000
initialise the repo
$ repo init
$ repo init -u https://chromium.googlesource.com/chromiumos/manifest.git --repo-url https://chromium.googlesource.com/external/repo.git [-g minilayout]
get the source code
$ repo sync -j4
getting/syncing the source code took a long time as it kept failing...
I am now in this position with the source code in code/
I will fill in gaps of instructions I missed later...
Create a chroot
make sure depot_tools/ is inside the folder code/: code/depot_tools
temporary put depot_tools in the path
export PATH=$PATH:depot_tools
$ cros_sdk
... this will take some time...
NOTICE: Mounted .../code/chroot.img on chroot
NOTICE: Downloading SDK tarball..
All done
INFO cros_sdk:make_chroot: Elapsed time (make_chroot.sh): 74m37s
cros_sdk:make_chroot: All set up. To enter the chroot, run:
$ cros_sdk --enter
CAUTION: Do *NOT* rm -rf the chroot directory; if there are stale bind
mounts you may end up deleting your source tree too. To unmount and
delete the chroot cleanly, use:
$ cros_sdk --delete
(cr) ((c62d307...)) [email protected] ~/trunk/src/scripts $
now comes the real stuff...
Notes -
some extra commands might be needed to get this working:
$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-get install linux-generic
$ sudo apt-get install fakeroot build-essential crash kexec-tools makedumpfile kernel-wedge
$ sudo apt-get install git-core libncurses5 libncurses5-dev libelf-dev asciidoc binutils-dev

Hello, My guide should fill in the blanks for you (Specifically the Over The Air Upgrades) - https://kmyers.me/blog/chromeos/a-g...s-distribution-with-ota-updates-and-crostini/

No, ChromiumOS is a operating system that either replaces your default operating system or that you dual boot into. It is not simply a application that you can install. If you want to run it without installing it, you could in theory build it yourself and convert the image to a virtual machine image and run it in Qemu or VirtualBox.
