# Arch Linux
|
|
|
|
[Arch Linux](https://archlinux.org/) is a rolling-release, general-purpose
|
|
[Linux](/wiki/linux/linux.md)
|
|
distribution.
|
|
Arch Linux uses the [pacman](./package_manager.md) package manager.
|
|
The Arch User Repositories (AUR) features community-made packages that can be
|
|
installed with different
|
|
[package manager that inlcude access to the AUR](/wiki/linux/arch-linux/package_manager.md).
|
|
|
|
## Installation
|
|
|
|
The installation of a basic Arch Linux system is described in the
|
|
[installation entry](/wiki/linux/arch-linux/installation.md).
|
|
The entry features a guide to install a system with a X server setup aswell as
|
|
programs for the most used tasks on a system.
|
|
|
|
### ISO Medium
|
|
|
|
For the installation usage of a simple USB key is advised.
|
|
This has to be flashed with the Arch ISO.
|
|
The ISO file can be found on the
|
|
[official website](https://www.archlinux.org/download/).
|
|
The iso can be written on an USB-stick using the command
|
|
`dd bs=4M if=<path to ISO> of=/dev/sdx conv=fsync oflag=direct status=progress`.
|
|
`<path to ISO>` points the command to the location of the ISO file
|
|
|
|
## Recommended Practices
|
|
|
|
The following articles describe steps to undertake to harden the system security
|
|
or setups and installation that are recommended for Arch Linux.
|
|
|
|
## Enable Microcode Updates
|
|
|
|
The microcode of Intel and AMD CPUs can be automatically updated by installing
|
|
the `amd-ucode` or `intel-ucode` package depending on your CPU.
|
|
Not all processors are supported, especially old ones can lead to problems.
|
|
It has to be confirmed that the processor is supported, if this is not the case
|
|
is possible for the next steps to break the functionality of the bootloader.
|
|
|
|
The following part assumes the system is installed with
|
|
[UEFI bootloader](/wiki/linux/arch-linux/installation.md#10-install-and-configure-uefi-bootloader)
|
|
similar to the [recommended guide](/wiki/linux/arch-linux/installation.md).
|
|
The microcode updates can then be enabled by adding the following line into
|
|
`/boot/loader/entries/arch.conf`:
|
|
|
|
```txt
|
|
initrd /<installed microcode package>.img
|
|
```
|
|
|
|
`<installed microcode package>` is either `amd-ucode` or `intel-ucode`.
