[WIP] Update Qubes route for 4.1.x
Created by: pterocles
Proposed changes to guide
Download and prepare Qubes USB drive for installation
sdX is the disk that Qubes OS will be installed on sdY is the USB that will contain the bootloader and the detached LUKS header file sdZ is the USB stick containing the Qubes OS installer
Boot into installation and press Ctrl + Alt + F2 to enter into terminal
Prepare your disk by first overwriting with random data
dd if=/dev/urandom of=/dev/sdX status=progress
Create LUKS header file
dd if=/dev/zero of=header.img bs=16M count=1
Write master key with passphrase to header file
cryptsetup luksFormat /dev/sdX --header header.img
Open the encrypted device
cryptsetup luksOpen /dev/sdX luks --header header.img
Create LVM on LUKS config
vgcreate qubes_dom0 /dev/mapper/luks
lvcreate -n swap -L 10G qubes_dom0
lvcreate -T -L 60G qubes_dom0/root-pool
lvcreate -T -l +100%FREE qubes_dom0/vm-pool
lvcreate -V60G -T qubes_dom0/root-pool -n root
lvcreate -V871G -T qubes_dom0/vm-pool -n vm
mkfs.ext4 /dev/qubes_dom0/vm Create filesystems on logical volumes
mkfs.ext4 /dev/mapper/qubes_dom0-root
mkswap /dev/mapper/qubes_dom0-swapPrepare USB boot
fdisk /dev/sdY
g enter
n enter
t enter
1 enter
w enter
mkfs.fat -F32 /dev/sdY1
Return to GUI and enter device configuration
press Ctrl + Alt + F6 select /dev/sdX select "I will configure partitioning" de-select "Encrypt my data" press "Done"
Return to terminal and mount filesystems
press Ctrl + Alt + F2
mount /dev/mapper/qubes_dom0-root /mnt
swapon /dev/mapper/qubes_dom0-swap
mkdir -p /mnt/boot/efi
mount /dev/sdY1 /mnt/boot/efiReturn to GUI and refresh the device list
press Ctrl + Alt + F6 click on the "Refresh" button to load created partitions click on qubes_dom0-root and select / as its mount point and check reformat as ext4 click on qubes_dom0-swap and select reformat as swap click on /dev/sdY1 then leave it alone press "Done"
If the installer finished successfully then do NOT reboot
press Ctrl + Alt + F2
cp header.img /mnt/sysimage/
cp -r /mnt/sysimage/boot /mnt/sysimage/boot.orig
rm -rf mnt/sysimage/boot/*Mount the live filesystem

Exit & reboot
Enter boot menu and select the UEFI GRUB bootloader to load detached LUKS Qubes OS.
During boot it may appear stuck, press any key to get to the disk decryption.
If you made it this far then remember that you will have to manually regenerate the initramfs with the new kernel after upgrading dom0.
