systemd-boot (efi,boot,arch)

A simple UEFI boot manager which execute configured EFI images.

Installing the EFI boot manager

1. check UEFI mode

   make sure your system has booted in UEFI mode and that UEFI variables are accessible.

   1 2	ls /sys/firmware/efi/efivars //or efivar --list

2. install into the esp

   esp will denote the ESP mountpoint,eg:/boot or /efi/

   1	bootctl install

   This will copy the systemd-boot boot loader to eht EFI partition: on a x64 architecture system /usr/lib/systemd/boot/efi/systemd-bootx64.efi will be copied to esp/EFI/systemd/-bootx64.eft and esp/EFI/BOOT/BOOTx64.EFI. It will then set systemd-boot as the default EFI application(default boot entry) loaded by the EFI BOOT Manager.

   note: If you want to separate the esp partition,use bootctl --esp-path=/efi-path --boot-path=/boot-path install

Updating the EFI boot manager

1. manual update

   1	bootctl --esp-path=/efi-path --boot-path=/boot-path update

2. automatic update

   placing the following pacman hook in the /etc/pacman.d/hooks/ directory:

   1 2 3 4 5 6 7 8 9 10

   vim /etc/pacman.d/hooks/100-systemd-boot.hook [Trigger] Type = Package Operation = Upgrade Target = systemd [Action] Description = Updating systemd-boot When = PostTransaction Exec = /usr/bin/bootctl update

Configuration

1. loader configuration

   there are some config options

   1 2 3 4 5 6 7

   default timeout editor auto-entries console-mode random-seed-mode always

   eg:A loader configuration example is provided below: esp/loader/loader.conf

   1 2 3 4

   default arch.conf timeout 4 console-mode max editor no

EFI shells or other EFI applications

1. loading from esp/loader/entries/xxxx.conf eg: /EFI/xxx.efi the relative path via esp
