But what if you requirements are simple? And you want the installation to be as simple as possible? Plain and simple no fuzz - boot Manjaro - that's it.
systemd-boot is a bootloader which do not get much attention on Manjaro - since most Manjaro installations is created using Calamares installer which in turn installs grub. I recall a setting for an iso-profile setting the
efi_bootloader="grub" - but it didn't work very well so I decided to learn how to implement systemd-boot the most simple way - later create a merge request to the tools.
First - I am assuming you know your device path - for the safety of less experienced readers - I am using a device path /dev/sdy you most likely do not find on your system.
Second - I am assuming you are using a root TTY as no commands is prefixed with sudo.
TIP: Don't use a graphical environment - switch to TTY - because the live system may lock screen and other unpleasant thing while you are using the terminal - thus breaking what ever you were doing.
Third - I will be using command line partitioning - no menu interfaces - pure command line.
Fourth - This guide will work for any device - it be internal, removable USB or otherwise attached to your system. To ease the pain of writing the same device over and over I made use of an environment variable - I assume you set the same too.
If your circumstances allows for it - you can use [ssh] to install remotely using another device on your network.
If you have not done so already open a root TTY and set the device variable - remember it only exist in the current shell
Ensure your device is not mounted anywhere
# umount -f "$INS"
The stuff that needs disclaimers - you are on your own kind of stuff.
# sgdisk --zap-all "$INS"
# sgdisk --mbrtogpt "$INS"
# sgdisk --new 1::+512M --typecode 1:ef00 --change-name 1:"EFI System" "$INS"
# sgdisk --new 2::: --typecode 2:8304 --change-name 2:"Linux x86-64 root" "$INS"
# wipefs -af "$INS"1 # wipefs -af "$INS"2
Format $esp partition using FAT32
# mkfs.vfat -vF32 "$INS"1
Format the the root partition using your preferred filesystem- If your device is flash based you can use f2fs which is created for flash or you can use ext4 which is a defacto standard for Linux.
# mkfs.f2fs "$INS"2
Mount your root partition on the systems temporary mountpoint
# mount "$INS"2 /mnt
Then create the folder for booting systemd ($esp)
# mkdir /mnt/boot
And mount the $esp partition
# mount "$INS"1 /mnt/boot
This article is only scratching the surface of the new system. We only install a basic bootable system using the base meta package, filesystem tools for f2fs along with kernel and some required tools - and don't forget network connectivity
# basestrap /mnt base f2fs-tools linux55 nano mkinitcpio bash-completion networkmanager systemd-boot-manager
Configuring the system is the tedious - extremely boring - but crucial part, usually abstracted by tools like Manjaro Architect.
# manjaro-chroot /mnt /bin/bash
The vconsole.conf file contains information about the type of keymap you are using - in this case a danish keymap - but it could us for a default US english keymap.
# echo KEYMAP=dk > /etc/vconsole.conf
The hostname file contains the name of your computer on a network - this must be unique - you can of course select another name
# echo manjaro > /etc/hostname
The hosts file contains information local to your system. The is almost empty - edit the file and append below IP addresses and the hostname from your hostname file
# nano /etc/hosts
127.0.0.1 localhost 127.0.1.1 manjaro.localdomain manjaro
The ever important system time - the example is for Denmark but it could be Europe/Paris if you live in that area.
# ln -sf /usr/share/zoneinfo/Europe/Copenhagen
Unix systems expects the hardware clock to run in UTC and the system then corrects the clock using the timezone information - this is a point where Windows and Linux disagree causing trouble for dual-booters - which we are not.
# hwclock --systohc
Enable the network and timesync (don't use
--now in chroot, it will fail)
# systemctl enable NetworkManager systemd-timesyncd
Now we create a locale configuration - this configuration defines system messages and how time, date and other units are displayed.
# nano /etc/locale.gen
Uncomment the locales you want to use - e.g. using English for messages and German for date and time uncomment both. In this example - again for Denmark.
To actually use preferences the necessary files needs generated - this is done using the
The locale.conf file contains a reference to the locale files just created. Please see the Arch Wiki page on locales for additional entries you can add.
# echo LANG=en_DK.UTF-8 > /etc/locale.conf
And finally set the root password
This is the interesting part you have worked yourself down to.
Use the mkinicpio command to generate the initramfs - it will copy the files to the boot ($esp) partition.
# mkinitcpio -P
Now install the systemd bootloader to the boot ($esp) partition
# bootctl --path=/boot install
The rest of the configuration can be done outside chroot - necessary to write a boot entry to your EFI firmware
For the bootloader to actually load we need create a configuration file to specify the kernel, initrd.
To avoid typos - use
ls to list the content of boot folder and pipe the output to the boot configuration
# ls /mnt/boot/init* /mnt/boot/vmlinuz* > /mnt/boot/loader/entries/manjaro.conf
Now open the file using nano
# nano /mnt/boot/loader/entries/manjaro.conf
Amend the file to look like this (the order of the lines are not important)
title Manjaro linux /vmlinuz-5.5-x86_64 initrd /initramfs-5.5-x86_64.img
This new configuration file is then added to the file loader.conf
# nano /mnt/boot/loader/loader.conf
This article does not take into account the amd/intel microcode and maintenance due to kernel upgrades or booting different kernels.
To learn more - read up on systemd-boot on the Arch Wiki.
Just a few things worth noting.
- With systemd-boot, we also need to handle microcode loading by hand in the entries
- It is probably worth pointing out that these entries will need to be added/updated as new kernels are installed and removed
- Lastly, systemd-boot-manager will handle both those things for you in an automated fashion. It can automate the installation of systemd-boot, the creation and removal of entries, the addition of microcode updates and has options setting defaults automatically. It has full support for luks/lvm/btrfs/zfs/etc.
Unmount your devices
# umount -R /mnt
If you are installing to an USB device - sync device before removing it
You have only scratched the surface and there is work to be done - installing xorg, applications, themes - what ever you fancy - it's really up to you how this adventure ends.
Have fun - I did.
