https://mchladek.me/post/arch-mbp/

Installation¶

Better InitFS

Make Bootable USB:

sudo dd bs=4M if=/path/to/arch.iso of=/dev/sdx

Install paru:

#Install Black arch
curl -O https://blackarch.org/strap.sh
chmod +x strap.sh
sudo ./strap.sh

#Install paru
pacman -S paru

Install List:

#Generate List of installed packages
pacman -Qqen > pkglist.txt

#Install List of packages
pacman -S - < pkglist.txt

Recover from bad boot¶

Mount encrypted Drive:

cryptsetup open /dev/sda3 root
mount /dev/mapper/lvm-root /mnt
arch-chroot /mnt
mount /sda1 /boot
bootctl update

Update microcode¶

Install Intel Package:

yay install intel-ucode

Update Bootloader:

>>> cat /boot/loader/entries/arch-mac-enc-lvm.conf 
title ArchLinux Encrypted
linux /vmlinuz-linux-macbook
initrd /intel-ucode.img
initrd /initramfs-linux-macbook.img
options cryptdevice=UUID=df915784-8700-4718-a4d9-7112e6bb7fbf:root root=/dev/mapper/lvm-root quiet rw hid_apple.iso_layout=0 libata.force=noncq resume=/dev/mapper/lvm-swap processor.ignore_ppc=1

Enable Hibernation¶

Enable Swap space:

sudo swapon --show # or `cat /proc/swaps`
sudo swapoff -a
sudo fallocate -l <SIZE>G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
sudo swapon --show # to verify changed size

Get UUID:

sudo swap-offset /swapfile
> <OFFSET>
sudo findmnt -no SOURCE,UUID -T /swapfile 
> <UUID>

Update GRUB:

#Update /etc/default/grub
`GRUB_CMDLINE_LINUX_DEFAULT="quiet splash resume=UUID=<UUID> resume_offset=<OFFSET>"`

# Create /etc/initramfs-tools/conf.d/resume
sudo update-grub
sudo update-initramfs -u -k all
