# Install Arch Linux
|
|
|
|
Install Arch Linux is thing I always want to do for my laptop/PC since I had my
|
|
laptop in ninth grade.
|
|
|
|
This is not a guide for everyone, this is just save for myself in a future and
|
|
for anyone who want to walk in my shoes.
|
|
|
|
## [Installation guide](https://wiki.archlinux.org/index.php/Installation_guide)
|
|
|
|
### Pre-installation
|
|
|
|
Check disks carefully:
|
|
|
|
```sh
|
|
lsblk
|
|
```
|
|
|
|
[USB flash installation medium](https://wiki.archlinux.org/index.php/USB_flash_installation_medium)
|
|
|
|
#### Verify the boot mode
|
|
|
|
Check UEFI mode:
|
|
|
|
```sh
|
|
ls /sys/firmware/efi/efivars
|
|
```
|
|
|
|
#### Connect to the internet
|
|
|
|
For wifi, use [iwd](https://wiki.archlinux.org/index.php/Iwd).
|
|
|
|
#### Partition the disks
|
|
|
|
[GPT fdisk](https://wiki.archlinux.org/index.php/GPT_fdisk):
|
|
|
|
```sh
|
|
cgdisk /dev/sdx
|
|
```
|
|
|
|
[Partition scheme](https://wiki.archlinux.org/index.php/Partitioning#Partition_scheme)
|
|
|
|
UEFI/GPT layout:
|
|
|
|
| Mount point | Partition | Partition type | Suggested size |
|
|
| ----------- | ------------------------------------- | ------------------------------ | -------------- |
|
|
| `/mnt/efi` | `/dev/efi_system_partition` | EFI System Partition | 512 MiB |
|
|
| `/mnt/boot` | `/dev/extended_boot_loader_partition` | Extended Boot Loader Partition | 1 GiB |
|
|
| `/mnt` | `/dev/root_partition` | Root Partition | |
|
|
|
|
Why not `/boot/efi`? See
|
|
[Lennart Poettering comment](https://github.com/systemd/systemd/pull/3757#issuecomment-234290236).
|
|
|
|
BIOS/GPT layout:
|
|
|
|
| Mount point | Partition | Partition type | Suggested size |

|
|
| | | BIOS boot partition | 1 MiB |
|
|
| `/mnt` | `/dev/root_partition` | Root Partition | |
|
|
|
|
LVM:
|
|

pvcreate /dev/sdaX
|
|
|
|
# Create volume groups
|
|
vgcreate RootGroup /dev/sdaX /dev/sdaY
|
|
|
|
# Create logical volumes
|
|
lvcreate -l +100%FREE RootGroup -n rootvol
|
|
```
|
|
|
|
Format:
|
|
|
|
```sh
|
|
# efi
|
|
mkfs.fat -F32 /dev/efi_system_partition
|
|
|
|

|
```sh
|
|
# root
|
|
mount /dev/root_partition /mnt
|
|
|
|
# root with btrfs

|
|
|
Always remember to check **dependencies** when install packages.
|
|
|
|
### System administration
|
|
|
|
[Sudo](https://wiki.archlinux.org/index.php/sudo):
|
|
|
|
```sh
|
|
pacman -Syu sudo
|
|
|
|
EDITOR=nvim visudo
|
|
# Uncomment group wheel
|
|
|
|
# Add user if don't want to use systemd-homed
|
|
useradd -m -G wheel -c "The Joker" joker
|
|
|
|
# Or using zsh
|
|
useradd -m -G wheel -s /usr/bin/zsh -c "The Joker" joker
|
|
|
|
# Set password
|
|
passwd joker
|
|
```
|
|
|
|
[systemd-homed (WIP)](https://wiki.archlinux.org/index.php/Systemd-homed):
|
|
|
|
```sh
|
|
systemctl enable systemd-homed.service
|
|
|
|
homectl create joker --real-name="The Joker" --member-of=wheel
|
|
|
|
# Using zsh
|
|
homectl update joker --shell=/usr/bin/zsh
|
|
```
|
|
|
|
**Note**: Can not run `homectl` when install Arch Linux. Should run on the first
|
|
boot.
