Pacman settings
sudo nano /etc/pacman.conf

Enable 32bit repo [once steam get's 64bit this repo will be uncessary]
uncomment color option /etc/pacman.conf and uncomment [multilib] repo

Add AUR repo

[archlinuxfr]
SigLevel = Never
Server = http://repo.archlinux.fr/$arch

Initiate pacman gpg keys
# pacman-key --init
# pacman-key --populate archlinu



Install yay AUR helper
# git clone https://aur.archlinux.org/yay.git
# cd yay
# makepgk -si

Install another AUR helper
# yay -S pikaur

Rankmirrors
# yay -S pacman-contrib
Back up the existing /etc/pacman.d/mirrorlist: 
# cp /etc/pacman.d/mirrorlist /etc/pacman.d/mirrorlist.backup

To uncomment every mirror, run the following sed line: 
# sed -i 's/^#Server/Server/' /etc/pacman.d/mirrorlist.backup

Rank the mirrors, here with the operand -n 6 to only output the 6 fastest mirrors: 
# rankmirrors -n 6 /etc/pacman.d/mirrorlist.backup > /etc/pacman.d/mirrorlist

Sync mirrors

Automatically clean the package cache after every pacman transaction.

Using Reflector to rank mirrors
# yay -S reflector

Back up the existing /etc/pacman.d/mirrorlist: 
# cp /etc/pacman.d/mirrorlist /etc/pacman.d/mirrorlist.backup

Verbosely rate and sort the five most recently synchronized mirrors by download speed, and overwrite the file /etc/pacman.d/mirrorlist: 
# reflector --verbose --latest 5 --sort rate --save /etc/pacman.d/mirrorlist


Pacman hook
Create a pacman hook that will run reflector and remove the .pacnew file created every time pacman-mirrorlist gets an upgrade. 
# mkdir /etc/pacman.d/hooks
# nano /etc/pacman.d/hooks/mirrorupgrade.hook
-------------------------------------------------------------------------------

Systemd service

This is an example of service unit that waits for the network to be up and online before running reflector:

Enable/Start service
# systemctl enable reflector.service

# sudo pacman -S xorg xorg-server xf86-input-libinput xf86-video-intel xorg-xinit xterm xorg-xclock xorg-twm git

Snapshots of root will allow a working copy of root be preserved as a backup while upgrading or testing the system

Display lv
# lvs

LVM snapshots commands for root snapshots of fresh install (this will also save luks headers)
# lvcreate -L 10GB -n snap-root -s vgArch/cryptroot

Reverting back to root snapshots
# lvconvert --merge vgArch/snap-root
Snapshots will be deleted after restart of the system

Removing root snapshots
# lvremove vgArch/snap-root

LVM snapshots commands for home snapshots and tar backup
# lvcreate -L 10GB -n snap-home -s vgArch/crypthome

Reverting back to home snapshots
# lvconvert --merge vgArch/snap-home
Snapshots will be deleted after restart of the system

Removing home snapshots
# lvremove vgArch/snap-home


Known Issues
shutting down the system with active snapshots may hang for some time. As a workaround a shorter job timeout can be set. Create a copy of /usr/lib/systemd/system/dm-event.service in /etc/systemd/system and insert JobTimeoutSec=10

Editing fstab and crypttab for auto-mount and auto-unlock options of externel encrypted usb 
Make mount point for external drive

# sudo mkdir /mnt/backup
Set chattr option so we can't write in the /mnt/backup dir while drive is not mounted
# sudo chattr +i .

Zero out drive
# dd if=/dev/zero of=/dev/sdX bs=4096 status=progress
Once done an error of no more space will display

Encrypting drive with passphrase first
# cryptsetup -c aes-xts-plain64 -s 512 -h sha512 -i 5000 luksFormat /dev/sdX
Type in capital YES
Enter in passphrase twice

Now create a keyfile to allow crypttab to auto-unlock the the encrypted drive when plugged in. 

Generate 20kb of random data for a keyfile for use with encrypting and unlocking lvm-vg02 with a keyfile. 
Which will be named lvm-vg02-data-key and located in root of usb installation disk
# dd if=/dev/urandom of=usb.key bs=1024 count=20

Add in key into external encrypted drive
# cryptsetup luksAddKey /dev/sdX usb.key


Find UUID
#cryptsetup luksDump /dev/sdX

Add mount point and options for /etc/crypttab

DNSMASQ setup

Installing and configure Samba
# sudo pacman -S samba kdenetwork-filesharing gvfs-smb

Create /etc/samba/smb.conf and add the following default values:
-----------------------------------------------------------------------------------------------------
# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options (perhaps too
# many!) most of which are not shown in this example
#
# For a step to step guide on installing, configuring and using samba, 
# read the Samba-HOWTO-Collection. This may be obtained from:
#  http://www.samba.org/samba/docs/Samba-HOWTO-Collection.pdf
#
# Many working examples of smb.conf files can be found in the 
# Samba-Guide which is generated daily and can be downloaded from: 
#  http://www.samba.org/samba/docs/Samba-Guide.pdf
#
# Any line which starts with a ; (semi-colon) or a # (hash) 
# is a comment and is ignored. In this example we will use a #
# for commentry and a ; for parts of the config file that you
# may wish to enable
#
# NOTE: Whenever you modify this file you should run the command "testparm"
# to check that you have not made any basic syntactic errors.

# This option is important for security. It allows you to restrict
