# Notes for installing archlinux
# UEFI boot: LVM on LUKS
#
# Based on Jason Wryan's instructions.
# See his full blog post:
# http://jasonwryan.com/blog/2013/01/25/uefi/

# check you are booted in uefi
efivar -l

### Set up disk.
# Nuke disk (just in case)
sgdisk -Z /dev/sdX

# Set disk partition alignment and clear all partition data
sgdisk -a 2048 -o /dev/sdX

# New partition for boot, 0 to 200M
sgdisk -n 1:0:+200M /dev/sdX

# The rest is for the LUKS partition
sgdisk -n 2:0:0 /dev/sdX

# Boot partition's type is EFI System
sgdisk -t 1:ef00 /dev/sdX

# LUKS partition is 'Linux filesystem'
sgdisk -t 2:8300 /dev/sdX

# Set partition names
sgdisk -c 1:bootefi /dev/sdX
sgdisk -c 2:root /dev/sdX

### Set up LUKS and encrypt sdX2
# The actual setup
cryptsetup --cipher aes-xts-plain64 --key-size 512 --hash sha512\
--iter-time 5000 --use-random --verify-passphrase luksFormat /dev/sdX2

# Mount the partition
cryptsetup luksOpen /dev/sdX2 cryptdisk

### Set up LVM on the LUKS partition
# setup logical volumes
pvcreate /dev/mapper/cryptdisk
pvdisplay

vgcreate vgroup /dev/mapper/cryptdisk
vgdisplay

# Partitioning. Customize this for yourself
lvcreate --size 30G --name lvroot vgroup
lvcreate --extents +100%FREE --name lvhome vgroup
lvdisplay

### Formatting partitions
# Boot should be vfat
mkfs.vfat -F32 /dev/sdX1
# The rest are ext4
mkfs.ext4 /dev/mapper/vgroup-lvroot
mkfs.ext4 /dev/mapper/vgroup-lvhome

### Mount the partitions
mount /dev/mapper/vgroup-lvroot /mnt
mkdir -p /mnt/boot/efi
mount -t vfat /dev/sdX1 /mnt/boot
mkdir /mnt/home
mount /dev/mapper/vgroup-lvhome /mnt/home

### Install base system ###
# Select a fast mirror
vim /etc/pacman.d/mirrorlist
# Install
pacstrap -i /mnt base base-devel

### Set up the fstab
genfstab -U -p /mnt >> /mnt/etc/fstab
# Make sure the fstab isn't totally broken
vim /mnt/etc/fstab

### Chroot into the new system
arch-chroot /mnt

### Misc modifications
# vi /etc/mkinitcpio.conf
# Add the following hooks
…encrypt lvm2 filesystems… shutdown…
# Add the following modules
vfat ext4 dm_mod dm_crypt aes_x86_64 i915
# generate new images
mkinitcpio -p linux

# add options to /etc/lvm/lvm.conf
issue_discards = 1

### Timezone (customize of course)
ln -s /usr/share/zoneinfo/America/Los_Angeles /etc/localtime

### Set hostname
echo bbq > /etc/hostname

### Set up wired networking (check interface with ip link)
systemctl enable dhcpcd@enp0s3.service

### Set up wireless networking dependencies
pacman -S iw wpa_supplicant dialog wpa_actiond

### Root password
passwd

# set up bootloader
bootctl install

# create conf
# /boot/loader/loader.conf
default arch
timeout 5

# create /boot/loader/entries/arch.conf
title Arch Linux
linux /vmlinuz-linux
initrd /initramfs-linux.img
options cryptdevice=/dev/sdX2:vgroup root=/dev/mapper/vgroup-lvroot ro


###### After reboot

### Set up user account
useradd -m -g users -G wheel -s /bin/bash angrygoats
passwd angrygoats


# Add to sudoers (uncomment wheel comment)
visudo

### Pacman stuff
# Set up multilib for 32 bit applications (uncomment multilib)
vi /etc/pacman.conf

### Install yaourt
(diy)

### Extra setup for installations inside virtualbox
pacman -S virtualbox-guest-utils
modprobe -a vboxguest vboxsf vboxvideo

# Add to startup as well
systemctl enable vboxservice

# Start vbox client
VBoxClient-all

# Add to ~/.xinitrc
(diy)

### Editor (gvim for clipboard support, use console vim provided)
pacman -S gvim

### Window management
### ALTERANTIVE (Awesome WM)
### pacman -S awesome vicious
### echo "exec awesome" >> ~/.xinitrc
### mkdir -p ~/.config/awesome/
### cp /etc/xdg/awesome/rc.lua ~/.config/awesome
pacman -S xorg-xinit xmonad xmonad-contrib
cat `exec xmonad` >> ~/.xinitrc

#### Extra: System repair via livecd quick commands
cryptsetup luksOpen /dev/sdX2 cryptdisk
mount /dev/mapper/vgroup-lvroot /mnt
mount -t vfat /dev/sdX1 /mnt/boot
arch-chroot /mnt
