Editing Installing Arch Linux

=LiveCD=
* [https://archlinux.org/download/ Download] the latest Archlinux ISO Image
* Copy image to USB drive
** Use [https://sourceforge.net/projects/win32diskimager/ Win32 Disk Imager] in Windows 
** OR use the following on linux:
    dd bs=4M if=path/to/archlinux.iso of=/dev/sdx status=progress oflag=sync
* Reboot and choose boot device in BIOS and boot the USB drive

=Presetup=
==Boot==
The following guide is for UEFI systems, see [[Installing Archlinux (Legacy)]] for MBR. If you have an existing UEFI bootloader somewhere, identify it and mount it somewhere to confirm you can find the efi/ folder. Once properly identified, make note of this partition's device name (ex. /dev/sdb1) and unmount it. If you do not have a UEFI partition and are starting fresh, ensure you partition/format ~300-500MB for one, it helps a lot in multi-boot environments.

==Disk setup==

===Partitions===
Swap is pretty much optional but if you want Hibernate, it's needed

* /dev/sda1
** /boot - 300MB - EFI Filesystem 
* /dev/sda3
** swap - 8.8G - Linux swap
* /dev/sda2
** / - therest - Linux filesystem

It's also helpful to mount separate drives as your /home or /opt directories. I tend to put Steam/Lutris libraries in /opt and have a drive dedicated to my home folder and configs. Other system mounts I tend to put in /mnt or get automounted once I get to a desktop

* use fdisk /dev/sd(diskletter)
* Delete any old partitions ('''''!!!EXCEPT EXISTING UEFI PARTITIONS!!!''''')
* Create new partitions like the one above
** For the above, make sda1 then sda3
* Ensure types are set appropriately
* Write the partition and exit
* Repeat for any other disk being used that needs erasing

===Format and Mount===
* Format target disks (cmd /dev/sda1-3)
** mkfs.ext4 for / and any others
** mkswap and swapon for swap
** mkfs.fat -F32 for NEW EFI partitions or /boot
* Mount devices and directories
** mount /dev/sda2 /mnt
** mkdir -p /mnt/boot && mount /dev/sda1 /mnt/boot
* Additional mounts can be done now with a modification of the following:
** mkdir -p /mnt/opt && mount /dev/sdb1 /mnt/opt
* Or Network Shares/CIFS stuff as well
** mkdir -p /mnt/mnt/share && mount -t cifs //shareserver/ /mnt/share/

==Update installer sources==
===Repos===
See [https://wiki.archlinux.org/index.php/Official_repositories Official] and [https://wiki.archlinux.org/index.php/Unofficial_user_repositories Unofficial] repos
====Multilib====
Needed for gaming on Steam
    echo "[multilib]
    Include = /etc/pacman.d/mirrorlist" >> /etc/pacman.conf

====Valveaur====
For Valve's maintained Arch repo and f-sync patch for the kernel
    echo "[valveaur]" >> /etc/pacman.conf
    echo "Server = <nowiki>http://repo.steampowered.com/arch/valveaur</nowiki>" >> /etc/pacman.conf
Update pacman keys
    pacman-key -r 8DC2CE3A3D245E64 --keyserver hkp://keyserver.ubuntu.com && pacman-key --lsign-key 8DC2CE3A3D245E64

====Kernels====
=====linux-amd-znver2=====
<pre>
[linuxkernels]
Server = http://nhameh.ovh/$repo/$arch
SigLevel = Optional TrustAll</pre>

=Install and Configure=
==Installation==
To install the system, we use pacstrap <target> <packages>
    pacstrap /mnt base{,-devel} linux{,-headers,-firmware} nano ntfs-3g sudo git amd-ucode grub efibootmgr os-prober 
* base/-devel
** Base system and development tools
* linux/-headers/-docs
** Now is a good time to setup [https://wiki.yawg.wtf/index.php?title=Installing_Archlinux#Repos Repos] on the new install in /mnt
** This is the kernel and headers (+docs)
** Alternatives: linux-zen, [https://aur.archlinux.org/packages/linux-vfio/ linux-vfio<sup>AUR</sup>], linux-fsync, [https://aur.archlinux.org/packages/linux-pf/ linux-pf<sup>AUR</sup>], linux-lts, [https://aur.archlinux.org/packages/linux-pds/ linux-pds<sup>AUR</sup>]

Note: this presumes ntfs partitions being used and an AMD CPU, you might need to modify that for other systems 

===Additional packages===
More packages can be found at [[Arch Packages]]

==Configure==
===Hostname===
    echo "$yourhostname" > /mnt/etc/hostname
    echo "127.0.0.1		$yourhostname.localdomain	$yourhostname" >> /mnt/etc/hosts
===Mounts/FSTAB===
    genfstab -U -p /mnt >> /mnt/etc/fstab
===Locale===
    echo "en_US.UTF-8 UTF-8" > /mnt/etc/locale.gen

=Post install and chroot=
Now we chroot into the new install and finish setting things up:
    arch-chroot /mnt
==Chroot==
===Language and Timezones===
    ln -s /usr/share/zoneinfo/US/Pacific /etc/localtime
    locale-gen
    export LANG=en_US.UTF-8
===Kernel===
    mkinitcpio -P
===Users===
* Change Root passwd
** passwd
* Create local user
** useradd -m -G wheel $user && passwd $user
** Uncomment the Wheel group line in /etc/sudoers
===Services===
Enable any necessary services
    systemctl enable sddm
    systemctl enable NetworkManager
    systemctl enable bluetooth

==Grub==
Replace /boot below with your efi directory folder if different
    grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=Arch
    grub-mkconfig -o /boot/grub/grub.cfg

==Yay==
Sometimes we need AUR packages:
    cd /home/$user && git clone https://aur.archlinux.org/yay.git && chown -R $user yay/ && cd yay
    su $user
    makepkg -si
    cd .. && rm -rf yay/
===Recommended Packages===
====Nvidia Beta====
    nvidia{-beta,-beta-dkms,-utils-beta,-settings-beta} opencl-nvidia-beta lib32{-nvidia-utils-beta,-opencl-nvidia-beta}
====Misc====
Mostly my firmware and overclocking things, but Downgrade is a life saver for when updates go wrong
    aic94xx-firmware wd719x-firmware downgrade zenmonitor zenpower-dkms zenstates-git cpupower-gui python-nvidia-ml-py3-git python-py3nvml

=Exit chroot and Cleanup=
Leave chroot
    exit
Unmount any extra drives first then unmount /mnt
<pre>umount /mnt/boot
umount /mnt/home
umount /mnt</pre>
You can now reboot

=Specific Scripts=
<pre> curl https://yawg.wtf/arch/.$buildname/0_start.sh > 0_start.sh && chmod +x 0_start.sh</pre>
