# ALMA - Arch Linux Mobile Appliance
|
|
|
|
This tool installs Arch Linux into a USB drive, making it a customized live Arch Linux bootable
|
|
drive. It was inspired by [this](http://valleycat.org/linux/arch-usb.html) article. The USB drive
|
|
should be bootable both by UEFI and legacy boot.
|
|
|
|
## Installation
|
|
|
|
You can either build the project using cargo build or install the `alma` package from AUR.
|
|
|
|
## Requirements
|
|
|
|
This tool should be ran from an exiting Arch Linux installations. It depends on the following tools:
|
|
|
|
* sgdisk
|
|
* partprobe
|
|
* Arch install scripts
|
|
* mkfs.fat
|
|
* mkfs.btrfs
|
|
|
|
Dependencies will be handled for you if you install alma from AUR.
|
|
|
|
## Usage
|
|
|
|
``` shell
|
|
sudo alma create /dev/disk/by-id/usb-Generic_USB_Flash_Disk-0:0
|
|
```
|
|
|
|
This will wipe the entire disk and create a bootable installation of Arch Linux. As a precaution,
|
|
this tool will refuse to work with drive paths which don't start with `/dev/disk/by-id/usb-`.
|
|
|
|
After the installation is done you can either boot from it immediately or use `arch-chroot` to
|
|
perform further customizations before your first boot.
|
|
|
|
## What exactly does it do?
|
|
|
|
This tool doesn't aspire to be a generic installer for Arch Linux. Instead, it does the minimum
|
|
steps required to create a bootable USB with a few tweaks.
|
|
|
|
1. Partition the disk as suggested [here](http://valleycat.org/linux/arch-usb.html). The last
|
|
partition will be formatted as BTRFS
|
|
1. Bootstrap the system using `pacstrap -c`. The `-c` flag will use the host's cache instead the
|
|
drive's cache, which will speed up things when you create multiple drives. This tool will install
|
|
the base system, grub, intel-ucode, NetworkManager and btrfs-progs
|
|
1. Generate initramfs without the `autodetect` hook
|
|
1. Set NetworkManager to start at boot
|
|
1. Install GRUB in both legacy and UEFI modes
