### Format Disk
|
|
#### For this example I will be using a sata disk (/dev/sda)
|
|
COMMANDS="$(echo -e "$FORMAT_DISK_COMMANDS" | grep -v \#)"
|
|
|
|
fdisk $DISK <<< "$COMMANDS"
|
|
|
|
### Format EFI Partition
|
|
#### The efi partition (mounted at /boot/efi) Needs to be formatted as fat32
|
|
mkfs.fat -F32 $EFI_PARTITION
|
|
|
|
### Format SWAP partition
|
|
mkswap $SWAP_PARTITION
|
|
### Activate swap partition
|
|
swapon $SWAP_PARTITION
|
|
|
|
### Format Root Partition
|
|
#### We will be formatting it with ext4 because that's the default for most use-cases, especially when new linux users are concerned
|
|
mkfs.ext4 $ROOT_PARTITION
|
|
|
|
### Mounting the root partition to begin setting up the partitions where they need to be
|
|
mount $ROOT_PARTITION /mnt
|
|
### Calling the --mkdir flag for mount to create the necessary directories so that it can mount
|
|
mount $EFI_PARTITION --mkdir /mnt/boot/efi
|
|
|
|
### Using pacstrap to install the necessities to be able to get a chroot env

|
|
base:
|
|
This is a meta-package. One that will handle installing many of the necessary programs to have a basic install of arch to chroot into
|
|
|
|
|
|
linux:
|
|
This is the actual kernel being installed. It will install the kernel & kernel-modules necessary to boot
|
|
|
|
|
|
linux-headers:
|
|
This is many other family of distros (Debian, RedHat, etc) would name linux-dev || linux-devel
|
|
|
|
This is a package that contains all of the kernel's header files for compiling modules for your distrobutions kernel.
|
|
|
|
|
|
linux-firmware:
|
|
This is another meta package that contains just about all of the firmware drivers you system may need. It is just a dump of firmware, not all of them will be needed for your system.
|
|
|
|
sudo:
|
|
A program needed for privelege escalation. Basically to provide a user of an admin group (most often wheel in most distrobutions) to be able to execute binaries that require root level permissions in you system.
|
|
|
|
Installing it here because it is not installed by default. An alternative is doas, a utility to perform the same funciton.
