linux or initrd followed by the relative path of the corresponding files in the ESP e.g.This parameter can be omitted if the root partition is assigned the correct Root Partition Type GUID as defined in Discoverable Partitions Specification and if the systemd mkinitcpio hook is present.įor Linux boot, you can also use linux instead of efi. See persistent block device naming for more information. Optional, but you will need at least root= dev rw if booting Linux where dev is a block device specifier for the root ( /) volume. options – space-separated command line options to pass to the EFI program or kernel parameters.Either this parameter or linux (see below) is required. efi – EFI program to start, relative to your ESP ( esp) e.g.machine-id – machine identifier from /etc/machine-id, shown only when multiple entries with same title and version exist.version – kernel version, shown only when multiple entries with same title exist.(Discuss in Talk:Systemd-boot#Potential removal of "Loader configuration" section) Similarly, entries in boot can only use files in boot. kernels, initramfs, images, etc.) in esp. Note that entries in esp can only use files (e.g. Systemd-boot will search for boot menu items in esp/loader/entries/*.conf and additionally in boot/loader/entries/*.conf if using XBOOTLDR. If the bootloader (during the entry selection) appears distorted/uses the wrong resolution you can try to set the console-mode to auto (uses heuristics to select the best resolution), keep (keeps the firmware provided resolution) or 2 (tries to select the first non-UEFI-standard resolution).A basic loader configuration file is located at /usr/share/systemd/bootctl/nf. If you have set timeout 0, the boot menu can be accessed by pressing Space.bootctl set-default "" and bootctl set-timeout "" can be used to clear the EFI variables overriding the default and timeout options, respectively.default and timeout can be changed in the boot menu itself and changes will be stored as EFI variables LoaderEntryDefault and LoaderConfigTimeout, overriding these options.systemd-boot does not accept tabs for indentation, use spaces instead.For better understanding of this hook, consult sbsign(1). Replace /path/to/keyfile.key and /path/to/certificate.crt with your signing key and certificate respectively. Target = usr/lib/systemd/boot/efi/systemd-boot*.efiĭescription = Signing systemd-boot EFI binary for Secure BootĮxec = /bin/sh -c 'while read -r i do sbsign -key /path/to/keyfile.key -cert /path/to/certificate.crt "$i" done ' If you have Secure Boot enabled, you may want to add a pacman hook to automatically sign the boot manager upon every upgrade of the package: etc/pacman.d/hooks/95-systemd-boot.hook ĭescription = Gracefully upgrading systemd-boot.Įxec = /usr/bin/systemctl restart rvice Rather than installing systemd-boot-pacman-hook, you may prefer to manually place the following file in /etc/pacman.d/hooks/: The package systemd-boot-pacman-hook AUR adds a pacman hook which is executed every time systemd is upgraded. efi.signed bootloader under /usr/lib/systemd/boot/efi/ allows rvice to update the bootloader without invoking Secure Boot signing tools. efi.signed files under /usr/lib/systemd/boot/efi/ before. Tip: bootctl install and bootctl update search. This will copy the systemd-boot EFI boot manager to the ESP: on an 圆4 architecture system /usr/lib/systemd/boot/efi/systemd-boot圆4.efi will be copied to esp/EFI/systemd/systemd-boot圆4.efi and esp/EFI/BOOT/BOOTX64.EFI, and systemd-boot will be set as the default EFI application. Use bootctl(1) to install systemd-boot to the ESP: This assumes that you have chrooted to the system's mount point. Throughout, esp will denote the ESP mountpoint, e.g. This can be verified by running efivar -list or, if efivar is not installed, by running ls /sys/firmware/efi/efivars (if the directory exists, the system is booted into UEFI mode.) To install systemd-boot, first make sure that the system is booted into UEFI mode and UEFI variables are accessible. Installation Installing the EFI boot manager Note that systemd-boot can only start EFI executables (e.g., the Linux kernel EFISTUB, UEFI shell, GRUB, or the Windows Boot Manager). It provides a textual menu to select the boot entry and an editor for the kernel command line. Systemd-boot, previously called gummiboot (German for "rubber dinghy"), is an easy-to-configure UEFI boot manager.
