|
This is a guide on how to install parabola that i created to have a reference for my eventual future installations on a librebooted system.
|
|
I decided to write this because I found that following the original guide in the Parabola wiki was not sufficent if you want to have an encrypted disk and no systemd in your system.
|
|
Still, this is to be considered just a recap of what you will need to to if you want to install Parabola this way, do not consider this official (or even unofficial) documentation at all.
|
|
|
|
some info on [Parabola GNU/Linux-libre](https://www.parabola.nu/)
|
|
|
|
I will assume that you already created a bootable drive of some kind with an image of Parabola CLI Edition that you can download from here: [download](https://wiki.parabola.nu/Get_Parabola)\
|
|
I won't cover how to do so beacuse there are already hundreds of guides that perfectly teach you how to do it on every system with every image using every technique available.
|
|
|
|
## Check if you have a UEFI machine or not
|
|
Type the following command to check if you have a UEFI machine or not, and keep that in mind, we will use this information later
|
|
```
|
|
ls /sys/firmware/efi/efivars
|
|
```
|
|
## Format your drive
|
|
The choice of partitions and filesystems is a matter of preference, and beyond the scope of this install guide. You can look at the Parabola wiki to know more.
|
|
If you already know what do you want and how you want it, you can skip this part.
|
|
|
|
Proceed to format the drive you be installing Parabola on. I use fdisk, the most basic things you need to know about it are:
|
|
type **d** to delete a partition (will ask number), type **n** to create a partition (will ask usual info), type **w** to confirm the changes.
|
|
|
|
Lets target the drive:
|
|
```
|
|
fdisk /dev/sdX
|
|
```
|
|
Assuming you deleted any existing partition, the next is to create two partitions, the first one will be a 1Gb partition and the second one will be the rest of the disk (or anyhow how much space yo want on your system)
|
|
This is just the way i do it, you might find your needs are different.
|
|
|
|
```
|
|
Command (m for help): n
|
|
Partition type
|
|
p primary (0 primary, 0 extended, 4 free)
|
|
e extended (container for logical partitions)
|
|
Select (default p):
|
|
|
|
Using default response p.
|
|
Partition number (1-4, default 1):
|
|
First sector (2048-30277631, default 2048):
|
|
Last sector, +/-sectors or +/-size{K,M,G,T,P} (2048-30277631, default 30277631): +1G
|
|
|
|
Created a new partition 1 of type 'Linux' and of size 1 GiB.
|
|
```
|
|
|
|
Then we are gonna create the second partition, you can press enter and use the default values for every option, you will have something similar to this:
|
|
|
|
```
|
|
Command (m for help): n
|
|
Partition type
|
|
p primary (0 primary, 0 extended, 4 free)
|
|
e extended (container for logical partitions)
|
|
Select (default p):
|
|
|
|
Using default response p.
|
|
Partition number (1-4, default 1):
|
|
First sector (2048-30277631, default 2048):
|
|
Last sector, +/-sectors or +/-size{K,M,G,T,P} (2048-30277631, default 30277631):
|
|
|
|
Created a new partition 1 of type 'Linux' and of size X.XX GiB.
|
|
```
|
|
Modify the last sector if you need a specific amount of memory or leave it blank to take the entire free space of your drive.
|
|
It might ask you to remote an already present signature, in that case just remote it by pressing **Y** when asked to.
|
|
|
|
## Filesystem of boot partition
|
|
|
|
We are now gonna put a filesystem on the first partition, I use FAT partitioning beacuse it is versatile since it's compatibile with both legacy boot and UEFI.
|
|
```
|
|
mkfs.fat -F32 /dev/sdX1
|
|
```
|
|
|
|
## Encrypt the second partition
|
|
To encrypt out partition we run the command:
|
|
```
|
|
cryptsetup luksFormat /dev/sdX2
|
|
```
|
|
You be ask to confirm the choice by typing **YES** and you will be asked to insert the passphrase for the partition.
|
|
|
|
## Decrypt sdX2
|
|
```
|
|
cryptsetup open /dev/sdX2 partition-name
|
|
```
|
|
We now decrypt the partition and assign a name to it (the name can be a random string, it will change later anyhow)
|
|
If we now run ```lsblk``` we should see something like this:
|
|
``
|
|
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
|
|
nvme0n1 259:0 0 476.9G 0 disk
|
|
├─nvme0n1p1 259:1 0 1G 0 part
|
|
└─nvme0n1p2 259:2 0 475.9G 0 part
|
|
└─partition-name 254:0 0 475.9G 0 crypt
|
|
|
|
## Create filesystem for partition-name
|
|
Create a [btrfs](https://wiki.archlinux.org/title/btrfs) partition on the decrypted partition
|
|
```
|
|
mkfs.btrfs dev/mapper/partition-name
|
|
```
|
|
|
|
## Mount both partition
|
|
Mount the two partitions starting with partition-name:
|
|
```
|
|
mount /dev/mapper/partition-name /mnt
|
|
```
|
|
Then create a directory called **boot**:
|
|
```
|
|
mkdir /mnt/boot
|
|
```
|
|
And then mount the boot partition in the boot folder:
|
|
```
|
|
mount /dev/sdX1 /mnt/boot
|
|
```
|
|
If you now run ```lsblk``` again you should see the partition correctly mounted:
|
|
```
|
|
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
|
|
nvme0n1 259:0 0 476.9G 0 disk
|
|
├─nvme0n1p1 259:1 0 1G 0 part /mnt/boot
|
|
└─nvme0n1p2 259:2 0 475.9G 0 part
|
|
└─partition-name 254:0 0 475.9G 0 crypt /mnt
|
|
```
|
|
## (optional) Change mirrors
|
|
You might want to change the mirrors order to make installation of packages faster by going into this file (use your favorite text editor):
|
|
```
|
|
/etc/pacman.d/mirrorlist
|
|
```
|
|
From the list, move the servers that are closer to you to the top so that they will be the first ones to be chosen.
|
|
|
|
## Install packages into the system
|
|
Install the needed packages into the ```/mnt``` partition, add what you know you will need:
|
|
```
|
|
pacstrap /mnt base base-devel linux-libre linux-libre-firmware btrfs-progs grub networkmanager cryptsetup lvm2 vim neovim
|
|
```
|
|
If youre in UEFI then add the following package: ```efibootmgr```
|
|
|
|
- base and base-devel:\
|
|
base is the basic system and all the tools related to it, base-devel is necessary to compile packages and other stuff
|
|
- linux-libre:\
|
|
the libre version of the linux kernel, with no binary blobs, obfuscated code, or code released under proprietary licenses
|
|
- linux-libre-firmware:\
|
|
Some hardware devices such as the popular NetGear WNA1100 (aka: Wireless-N 150, aka: Atheros AR9271) require firmware (eg: ath9k_htc) from the linux-libre-firmware package
|
|
- grub:\
|
|
the boot loader
|
|
- networkmanager:\
|
|
internet 'n stuff
|
|
- cryptsetup and lvm2:\
|
|
packages needed for encrypting and decrypting the drive
|
|
- vim and neovim:\
|
|
i mean you know why
|
|
|
|
## Chroot into your system
|
|
```
|
|
arch-chroot /mnt bash
|
|
```
|
|
|
|
## Set the timezone and set the hardware clock
|
|
just run:
|
|
```
|
|
ln -s /usr/share/zoneinfo/Europe/Rome /etc/localtime
|
|
```
|
|
|
|
Change country adn city based on your correct timezone
|
|
Then synch the hardware clock with the system clock:
|
|
```
|
|
hwclock --systhoc
|
|
```
|
|
|
|
## Setup keyboard layout and language
|
|
Edit the locale.gen file:
|
|
```
|
|
nvim /etc/locale.gen
|
|
```
|
|
Uncomment the your langage and layout of choice
|
|
|
|
Edit the file locale.conf:
|
|
```
|
|
nvim /etc/locale.conf
|
|
```
|
|
I will add the setup for the US keyboard but you might want a different layout:
|
|
```
|
|
export LANG="en_US.UTF-8"
|
|
export LC_COLLATE="C"
|
|
```
|
|
Run the locale-gen command:
|
|
```
|
|
locale-gen
|
|
```
|
|
## Name your computer
|
|
Run:
|
|
```
|
|
echo "myhostname" > /etc/hostname
|
|
```
|
|
|
|
change **myhostname** with your desired name, then edit the following file:
|
|
```
|
|
nvim /etc/hosts
|
|
```
|
|
and add the follwing lines:
|
|
```
|
|
127.0.0.1 localhost
|
|
::1 localhost
|
|
127.0.1.1 myhostname.localdomain myhostname
|
|
```
|
|
|
|
## Enable NetworkManager service
|
|
run:
|
|
```
|
|
systemctl enable NetworkManager.service
|
|
```
|
|
|
|
## Add a user and set his groups and password
|
|
First add a password to your root with:
|
|
```
|
|
passwd
|
|
```
|
|
Then create a new user:
|
|
```
|
|
useradd -G wheel -m user
|
|
```
|
|
this way a user by the name of **user** has been created, added to the wheel group and a home directory has been created for him
|
|
Set the user user password:
|
|
```
|
|
passwd user
|
|
```
|
|
|
|
## Edit the mkinitcpio configuration
|
|
Edit the **mkinitcpio.conf** file:
|
|
```
|
|
nvim /etc/mkinitcpio.conf
|
|
```
|
|
look for the line in which hooks are declared, it is going be like this:
|
|
```
|
|
HOOKS=(base udev autodetect modconf kms keyboard keymap consolefont block filesystem fsck)
|
|
```
|
|
add to the hooks **encrypt** and **lvm2**:
|
|
```
|
|
HOOKS=(base udev autodetect modconf kms keyboard keymap consolefont block encrypt lvm2 filesystem fsck)
|
|
```
|
|
**Optionally** you can add the following modules to same mkinitcpio.conf file:
|
|
```
|
|
hid usbhid hid_generic ohci_pci
|
|
```
|
|
If, at the end of the installation, the keyboard is not working during the decryption of the partition\
|
|
|
|
Update the conf by typing:
|
|
```
|
|
mkinitcpio -p linux-libre
|
|
```
|
|
|
|
## Make the system able to decrypt the partition
|
|
Start by exiting the partition:
|
|
```
|
|
exit
|
|
```
|
|
Create an fstab and output it in the correct place:
|
|
```
|
|
# genfstab -p /mnt >> /mnt/etc/fstab
|
|
```
|
|
use **-U** or **-L** to define by UUID or labels, respectively
|
|
|
|
Take the output of **lsblk -f** in put it in the following file:
|
|
```
|
|
lsblk -f >> /mnt/etc/default/grub
|
|
```
|
|
Go back into your system:
|
|
```
|
|
arch-chroot /mnt bash
|
|
```
|
|
|
|
## Edit GRUB to make the system able to encrypt and decrypt the partition
|
|
Enter the following file:
|
|
```
|
|
nvim /etc/default/grub
|
|
```
|
|
At the end of the file you will find the output of our **lsblk -f** command, it will be something similar to this:
|
|
```
|
|
NAME FSTYPE FSVER LABEL UUID FSAVAIL FSUSE% MOUNTPOINTS
|
|
sdb
|
|
nvme0n1
|
|
├─nvme0n1p1 [UUID_0] 862.4M 16% /boot
|
|
└─nvme0n1p2 [UUID_1]
|
|
└─cryptlvm [UUID_2] 431.2G 9% /
|
|
```
|
|
You will only need the two UUIDs: **[UUID_1]** and **[UUID_2]**
|
|
|
|
|
|
And at the top of this file there will be a line that looks like this:
|
|
```
|
|
GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 quiet"
|
|
```
|
|
Now, take the UUID of the encrypted partition (in this case the **UUID_1**) and add the following to the GRUB_CMDLINE_LINUX_DEFAULT:
|
|
```
|
|
cryptdevice=UUID=[UUID_1]:cryptlvm
|
|
```
|
|
It will look something like this:
|
|
```
|
|
cryptdevice=UUID=33dd1b52-a543-4143-8bf8-004390e411e0:cryptlvm
|
|
```
|
|
Take the UUID of the decrypted partition (in this case the **UUID_2**) and add the following to the GRUB_CMDLINE_LINUX_DEFAULT:
|
|
```
|
|
root=UUID=[UUID_2]
|
|
```
|
|
It will look something like this:
|
|
```
|
|
root=UUID=b720a64e-fdf2-462e-9231-d1a35ae2654e
|
|
```
|
|
the **GRUB_CMDLINE_LINUX_DEFAULT** should look like this:
|
|
```
|
|
GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 quiet cryptdevice=UUID=33dd1b52-a543-4143-8bf8-004390e411e0:cryptlvm root=UUID=b720a64e-fdf2-462e-9231-d1a35ae2654e"
|
|
```
|
|
|
|
## Install Grub bootloader
|
|
Install GRUB for UEFI devices:
|
|
|
|
**esp** denotes the mountpoint of the EFI system partition
|
|
```
|
|
grub-install --target=x86_64-efi --efi-directory=[esp] --bootloader-id=grub
|
|
```
|
|
|
|
Install GRUB for legacy BIOS devices
|
|
```
|
|
grub-install /dev/sdX
|
|
```
|
|
Then create the grub configuration:
|
|
```
|
|
grub-mkconfig -o /boot/grub/grub.cfg
|
|
```
|
|
|
|
Now you can unmount your partitions, remove your bootable device and reboot the system.
|
|
You now a have a fully libre system, you chad.
|
|
|
|
## Migrate to Open-RC
|
|
For maximum chad-status you have to remote systemD in favour of Open-RC, the Parabola wiki has a section on how to do so [HERE](https://wiki.parabola.nu/OpenRC)
