Artix install with btrfs, encryption, and hibernation

I had been wanting to reinstall my linux system for a while, so I wrote this blog post while installing it. When installing the system, I read the artix and the arch wiki, this blog post, watched this luke smith video, I also watched some videos by EF - Linux Made Simple and just googled stuff in general. Even though I'm gonna be writing as if this post was a guide on how to install artix or arch, this post isn't really a guide, but rather just a way for me to document the way I installed my system in case I want to reinstall it, and this could be helpful to someone who is doing a similar setup, so don't blindly follow everything I do here.

I'm gonna use artix with the runit init system. I wanna use btrfs so that I can use snapshots in case I fuck something up. Since I'm gonna dual boot windows (I already have windows installed, I'm only reinstalling artix), I'm gonna setup hibernation so that I can switch systems without having to close my stuff. Also I'm gonna do encryption bcuz I do illicit things on the internet :> (this is a joke, the most illicit thing I've done on the internet was to spread huge amounts of misinformation)

Also note that I'm using uefi, if you're on bios the setup will differ in some aspects

Download the artix iso, burn it to a usb drive by using the dd command (or use a program such as balena etcher if you're on windows), and boot from it. I usually download the xfce version of the artix iso so that I can have a graphical environment while I install the system.

Anyways the partition scheme is gonna be like this:

Windows partitions:
/dev/sda1 <- that's window's efi partition, so I'm gonna have 2 efi partitions, I know that you can have just one when you're dual booting but I'm gonna leave it with 2 boot partitions anyways cuz im stupid
/dev/sda2
/dev/sda3
/dev/sda4

Linux partitions:
/dev/sda5 <- efi partition
/dev/sda6 <- main partition

The linux efi partition is gonna be of 500M, and the main partition is gonna be of 500G. I'm not gonna use a swap partition, and instead I'm gonna use a swapfile

I usually partition the disk using cfdisk

Now that the system is partitioned, format the efi partition by running mkfs.fat -F32 /dev/sda5, encrypt the main partition by running cryptsetup luksFormat /dev/sda6 and open the encrypted partition by running cryptsetup luksOpen /dev/sda6 cryptroot, and now we can format the main partition by running mkfs.btrfs /dev/mapper/cryptroot

Now mount the main partition:
mount /dev/mapper/cryptroot /mnt

Create the btrfs subvolumes in /mnt
cd /mnt
btrfs subvolume create @
btrfs subvolume create @home
btrfs subvolume create @swap
btrfs subvolume create @snapshots
btrfs subvolume create @var_log

Unmount /mnt, and then mount the boot partition and the subvolumes
cd ..
umount /mnt
mount -o noatime,compress=zstd,space_cache=v2,subvol=@ /dev/mapper/cryptroot /mnt
mkdir -p /mnt/{boot,home,.snapshots,var/log,swap}
mount -o noatime,compress=zstd,space_cache=v2,subvol=@home /dev/mapper/cryptroot /mnt/home
mount -o noatime,compress=zstd,space_cache=v2,subvol=@snapshots /dev/mapper/cryptroot /mnt/.snapshots
mount -o noatime,compress=zstd,space_cache=v2,subvol=@var_log /dev/mapper/cryptroot /mnt/var/log
mount -o noatime,subvol=@swap /dev/mapper/cryptroot /mnt/swap
mount /dev/sda5 /mnt/boot

For this setup I'm gonna be using the zstd compression algorithm, you can check out the other compression algorithms here.

Run chattr +C /mnt/swap to make it not be snapshotted and then create the swapfile
cd /mnt/swap
dd if=/dev/zero of=./swapfile bs=1M count= <- size of your swapfile status=progress
chmod 600 ./swapfile
mkswap -U clear ./swapfile
swapon ./swapfile

Once you've done that, you can install the system by running
basestrap -i /mnt base base-devel runit elogind-runit linux linux-firmware grub efibootmgr os-prober lvm2 lvm2-runit cryptsetup networkmanager networkmanager-runit btrfs-progs dosfstools mtools git vim

In this installation, I'm gonna be using grub as the boot loader, I really wanna try refind but since I'm doing things such as encryption and I'm also gonna do hibernation, I'm just gonna stick to grub because I don't really know how refind works, and learning how to use a new bootloader would make things a lot more complicated

Generate the filesystem table
fstabgen -U /mnt >> /mnt/etc/fstab

Now chroot into the system
artix-chroot /mnt bash

Setup the timezone
ln -s /usr/share/zoneinfo/YourRegion/Your_Timezone /etc/localtime
hwclock --systohc

For the localization, uncomment the locales you're gonna use in /etc/locale.gen, run locale-gen and put
export LANG="your locale"
export LC_COLLATE="C"
in your /etc/locale.conf

Set your hostname
echo "yourhostname" > /etc/hostname

And put this in your /etc/hosts:

127.0.0.1        localhost
::1              localhost
127.0.1.1        yourhostname.localdomain yourhostname
