sda1 100M EFI tipo1

sda3 o resto linux padrão

Criando o luks

cryptsetup luksFormat /dev/sda3
cryptsetup luksOpen /dev/sda3 cryptroot

Bom agora vamos no LVM

o live capaz de não ter, então:

apt update
apt install lvm2

lsblk

Primeiro o volume físico

vgcreate vg00 /dev/mapper/cryptroot
vgdisplay vg00

Agora os volumes lógicos

lvcreate -n raiz -L 33G vg00
lvcreate -n home -l 100%FREE vg00

lvdisplay
lsblk

Criando os sistemas de arquivos

mkfs.vfat /dev/sda1
mkfs.ext4 /dev/sda2
mkfs.ext4 /dev/mapper/vg00-raiz
mkfs.ext4 /dev/mapper/vg00-home

Montando...

mkdir /novo
mount /dev/mapper/vg00-raiz /novo
mkdir /novo/boot/
mount /dev/sda2 /novo/boot

Abrindo os tar

cd /novo
tar -xvf /media/user/externo/antigo-barra.tar

mount /dev/mapper/vg-00-home /novo/home
cd /novo/home
tar -xvf /media/user/externo/antigo-home.tar

cd /novo/boot
tar -xvf /media/user/externo/antigo-boot.tar

Preparando para UEFI

mkdir /novo/boot/efi
mount /dev/sda1 /novo/boot/efi

O chroot

mount --bind /proc /novo/proc
mount --bind /dev /novo/dev
mount --bind /dev/pts /novo/dev/pts
mount --bind /sys /novo/sys

chroot /novo

Já no sistema

apt update
apt install arch-install-scripts

para ajudar no fstab

apt purge grub-common grub-pc grub-pc-bin grub2-common

apt install grub-efi-amd64
grub-install /dev/sda`

Checando UUIDs

blkid

Olhando a conf da cripto anterior

cat /etc/crypttab

sda5_crypt UUID=a43578ce-2511-47df-b4fd-2636f1b5e8e none luks,discard

Preparando a nova

echo "cryptroot UUID=696dbd-....4bb810 none luks,discard" > /etc/crypttab`

Para o initrd poder ser capaz de decriptografar

cp /usr/share/initramfs-tools/hooks/cryptkeyctl /etc/initramfs-tools/hooks

Agora precisa editar o /etc/default/grub

GRUB_CMDLINE_LINUX="root=/dev/mapper/cryptroot cryptdevice=UUID=696dbd1c-9fae-4604-b48b-6c66784bb810:cryptroot"`

GRUB_ENABLE_CRYPTODISK=y

update-initramfs -u -k all

erros:

update-initramfs: Generating /boot/initrd.img-4.19.0-8-amd64
**W: Couldn't identify type of root file system for fsck hook**
W: Possible missing firmware /lib/firmware/nvidia/gv100/acr/ucode_load.bin for module nouveau

Descobrimos depois que:

  cp /proc/mounts /mnt/etc/mtab

Arruamando fstab

genfstab -U / > /etc/fstab
update-grub
update-initramfs -u -k all

Errado: GRUB_CMDLINE_LINUX="root=/dev/mapper/VG-00-raiz cryptdevice=UUID=696dbd1c-9fae-4604-b48b-6c66784bb810:cryptroot"

Corrigido: GRUB_CMDLINE_LINUX="root=/dev/mapper/vg00-raiz cryptdevice=UUID=696dbd1c-9fae-4604-b48b-6c66784bb810:cryptroot"

update-grub fica parado.

Errado: GRUB_CMDLINE_LINUX="root=/dev/mapper/VG-00-raiz cryptdevice=/dev/sda3:cryptroot"

Corrigido: GRUB_CMDLINE_LINUX="root=/dev/mapper/vg00-raiz cryptdevice=/dev/sda3:cryptroot"

Bem, não vi nada diferente do que acho que deva ser o certo! vamos nos preparar para o boot.

ctrl-d

umount /novo/boot/efi
umount /novo/boot/
umount /novo/proc
umount /novo/dev/pts
umount /novo/dev
umount /novo/sys
umount /novo/home
umount /novo

Pequenos problemas para dar gosto!

hehe!! pior que agora achei um artigo dizendo... Update grub in a chroot environment with root on a luks encrypted volume I looks like you forgot to create a proper /etc/mtap file

 cp /proc/mounts /mnt/etc/mtab

Boot hd.

grub>ls
(proc) (hd0) (hd0,gpt3) (hd0,gpt2) (hd0,gpt1)`

linux (hd0,gpt2)/vmlinuz-4.19.0-8-md64 root=/dev/mapper/vg00-raiz cryptdevice=/dev/sda3:cryptroot
initrd (hd0,gpt2)/initrd.img-4.19.0-8-amd64

GRUB_CMDLINE_LINUX="root=/dev/mapper/vg00-raiz cryptdevice=UUID=696dbd1c-9fae-4604-b48b-6c66784bb810:cryptroot"

GRUB_CMDLINE_LINUX="root=/dev/mapper/vg00-raiz cryptdevice=/dev/sda3:cryptroot"

linux (hd0,gpt2)/vmlinuz-4.19.0-8-md64 root=/dev/mapper/vg00-raiz cryptdevice=/dev/sda3:cryptroot init=/bin/bash
initrd (hd0,gpt2)/initrd.img-4.19.0-8-amd64

Bootado:

mount -o remount,rw /

bom, então arruma o /etc/default/grub trocando o VG pelo vg00

mount -a
update-grub
genfstab -U / > /etc/fstab

update-initramfs -u -k all

Problema no .Xauthority

Não lembrei como resolver fomos na ignorância

   apt purge lightdm
   apt install lighdm`

Tudo certo, até a próxima!

capaz que se resolva com:

su - lightdm
xauth generate :0 . trusted

Boas dicas para serem testadas:

insmod luks
cryptomount (hd1,gpt3)
set root=(crypto0)
configfile (crypto)/boot/grub/grub.cfg
