From 8d092270d28d82aa5623bcde55a2ee85129ac1f1 Mon Sep 17 00:00:00 2001 From: Bob van der Linden Date: Sun, 26 Oct 2014 21:29:04 +0100 Subject: nixos: iso-image: use syslinux bootloader for USB booting support This changes the bootloader for iso generation from Grub to syslinux. In addition this adds USB booting support, so that "dd" can be used to burn the generated ISO to USB thumbdrives instead of needing applications like UnetBootin. --- .../installer/cd-dvd/installation-cd-base.nix | 3 + nixos/modules/installer/cd-dvd/iso-image.nix | 132 ++++++++++----------- 2 files changed, 66 insertions(+), 69 deletions(-) (limited to 'nixos/modules/installer/cd-dvd') diff --git a/nixos/modules/installer/cd-dvd/installation-cd-base.nix b/nixos/modules/installer/cd-dvd/installation-cd-base.nix index b723a91e4f35..4896eee29084 100644 --- a/nixos/modules/installer/cd-dvd/installation-cd-base.nix +++ b/nixos/modules/installer/cd-dvd/installation-cd-base.nix @@ -36,6 +36,9 @@ with lib; # EFI booting isoImage.makeEfiBootable = true; + # USB booting + isoImage.makeUsbBootable = true; + # Add Memtest86+ to the CD. boot.loader.grub.memtest86.enable = true; diff --git a/nixos/modules/installer/cd-dvd/iso-image.nix b/nixos/modules/installer/cd-dvd/iso-image.nix index 39db7d9b8f72..57e1601a87b4 100644 --- a/nixos/modules/installer/cd-dvd/iso-image.nix +++ b/nixos/modules/installer/cd-dvd/iso-image.nix @@ -8,45 +8,39 @@ with lib; let - # The Grub image. - grubImage = pkgs.runCommand "grub_eltorito" {} + # The configuration file for syslinux. + baseIsolinuxCfg = '' - ${pkgs.grub2}/bin/grub-mkimage -p /boot/grub -O i386-pc -o tmp biosdisk iso9660 help linux linux16 chain png jpeg echo gfxmenu reboot - cat ${pkgs.grub2}/lib/grub/*/cdboot.img tmp > $out - ''; # */ - - - # The configuration file for Grub. - grubCfg = - '' - set default=${builtins.toString config.boot.loader.grub.default} - set timeout=${builtins.toString config.boot.loader.grub.timeout} - - if loadfont /boot/grub/unicode.pf2; then - set gfxmode=640x480 - insmod gfxterm - insmod vbe - terminal_output gfxterm - - insmod png - if background_image /boot/grub/splash.png; then - set color_normal=white/black - set color_highlight=black/white - else - set menu_color_normal=cyan/blue - set menu_color_highlight=white/blue - fi - - fi - - ${config.boot.loader.grub.extraEntries} + SERIAL 0 38400 + UI vesamenu.c32 + MENU TITLE NixOS + MENU BACKGROUND /isolinux/background.png + + LABEL boot + MENU LABEL Boot NixOS + LINUX /boot/bzImage init=${config.system.build.toplevel}/init ${toString config.boot.kernelParams} + INITRD /boot/initrd + + LABEL chain + MENU LABEL Boot existing OS + COM32 chain.c32 + APPEND hd0 0 + + LABEL reboot + MENU LABEL Reboot + COM32 reboot.c32 + + LABEL poweroff + MENU LABEL Power Off + COM32 poweroff.c32 ''; + isolinuxCfg = baseIsolinuxCfg + (optionalString config.boot.loader.grub.memtest86.enable isolinuxMemtest86Entry); # The efi boot image efiDir = pkgs.runCommand "efi-directory" {} '' - mkdir -p $out/efi/boot - cp -v ${pkgs.gummiboot}/lib/gummiboot/gummiboot${targetArch}.efi $out/efi/boot/boot${targetArch}.efi + mkdir -p $out/EFI/boot + cp -v ${pkgs.gummiboot}/lib/gummiboot/gummiboot${targetArch}.efi $out/EFI/boot/boot${targetArch}.efi mkdir -p $out/loader/entries echo "title NixOS LiveCD" > $out/loader/entries/nixos-livecd.conf echo "linux /boot/bzImage" >> $out/loader/entries/nixos-livecd.conf @@ -152,6 +146,22 @@ in ''; }; + isoImage.makeUsbBootable = mkOption { + default = false; + description = '' + Whether the ISO image should be bootable from CD as well as USB. + ''; + }; + + isoImage.splashImage = mkOption { + default = pkgs.fetchurl { + url = https://raw.githubusercontent.com/NixOS/nixos-artwork/5729ab16c6a5793c10a2913b5a1b3f59b91c36ee/ideas/grub-splash/grub-nixos-1.png; + sha256 = "43fd8ad5decf6c23c87e9026170a13588c2eba249d9013cb9f888da5e2002217"; + }; + description = '' + The splash image to use in the bootloader. + ''; + }; }; @@ -166,7 +176,7 @@ in # !!!
