Contents
What is Archboot?
- Archboot is a set of scripts to generate bootable media for CD/USB/PXE.
- It is designed for installation or rescue operation.
- It only runs in RAM, without any special filesystems like squashfs, thus it is limited to the RAM which is installed in your system.
Install archboot from the official repositories.
The difference to the archiso install media
- It provides an additional interactive setup and quickinst script.
- It contains [core] repository on media.
- It supports UEFI_CD boot.
- It runs a modified Arch Linux system in initramfs.
- It is restricted to RAM usage, everything which is not necessary like
- man or info pages etc. is not provided.
- It doesn't mount anything during boot process.
- It supports remote installation through ssh.
Archboot ISO Releases
- Hybrid image files and torrents are provided, which include i686/x86_64 and [core] repository,
- network labeled images don't include [core] repository.
- Please check md5sum before using it.
- Download 2013.08 „2k13-R2“ / Changelog / Forum thread
- kernel: 3.10.9
- pacman: 4.1.2
- RAM recommendations: 512 MB
Burning Release
Hybrid image file is a standard CD-burnable image and also a raw disk image.
- Can be burned to CD(RW) media using most CD-burning utilities.
- Can be raw-written to a drive using 'dd' or similar utilities. This method is intended for use with USB thumb drives.
'dd if=<imagefile> of=/dev/<yourdevice> bs=1M'
PXE booting / Rescue system
Download 2013.08 „2k13-R2“ needed files from the directory.
- vmlinuz_i686 + initramfs_i686.img (i686)
- vmlinuz_x86_64 + initramfs_x86_64.img(x86_64)
- For PXE booting add the kernel and initrd to your tftp setup and you will get a running installation/rescue system.
- For Rescue booting add an entry to your bootloader pointing to the kernel and initrd.
Supported boot modes of Archboot media
- It supports BIOS booting with syslinux.
- It supports UEFI/UEFI_CD booting with gummiboot and EFISTUB.
- It supports Secure Boot with prebootloader.
- It supports grub(2)'s iso loopback support.
- variables used (below for example):
- iso_loop_dev=PARTUUID=XXXX
- iso_loop_path=/blah/archboot.iso
menuentry "Archboot" --class iso { loopback loop (hdX,X)/<archboot.iso> linux (loop)/boot/vmlinuz_x86_64 iso_loop_dev=/dev/sdXX iso_loop_path=/<archboot.iso> initrd (loop)/boot/initramfs_x86_64.img }
- It supports booting using syslinux's memdisk (only in BIOS mode).
menuentry "Archboot Memdisk" { linux16 /memdisk iso initrd16 hd(X,X)/<archboot.iso> }
How to do a remote installation with ssh?
- During boot all network interfaces will try to obtain an IP address through dhcp.
- root password is not set by default! If you need privacy during installation set a password.
'ssh root@<yourip>'
Interactive setup features
- Media and Network installation mode
- Changing keymap and consolefont
- Changing time and date
- Setup network with netctl
- Preparing storage disk, like auto-prepare, partitioning, GUID (gpt) support, 4k sector drive support etc.
- Creation of software raid/raid partitions, lvm2 devices and luks encrypted devices
- Supports standard linux,raid/raid_partitions,dmraid/fakeraid,lvm2 and encrypted devices
- Filesystem support: ext2/3/4, btrfs, f2fs, nilfs2, reiserfs,xfs,jfs,ntfs-3g,vfat
- Name scheme support: PARTUUID, PARTLABEL, FSUUID, FSLABEL and KERNEL
- Mount support of grub(2) loopback and memdisk installation media
- Package selection support
- hwdetect script is used for preconfiguration
- Auto/Preconfiguration of fstab, kms mode, mkinitcpio.conf, systemd, crypttab and mdadm.conf
- Configuration of basic system files
- Setting root password
- grub(2) (BIOS and UEFI), refind-efi, gummiboot, syslinux (BIOS and UEFI) bootloader support
Bootparameters
General boot parameters
- earlymodules
- load modules before hooks are executed
- Usage:
- earlymodules=<comma-separated-array>
- earlymodules=ahci,ehci-hcd
- disablehooks
- disable a hook which is run during bootup
- Usage:
- disablehooks=<comma-separated-array>
- disablehooks=arch_floppy,arch_cdrom
- root
- Using this option will boot you into your specified existing system.
- Usage:
- root=/dev/<your-root-of-installed-system>
- root=/dev/sda3
- rootflags
- Using this option will pass special mount options for your root device
- Usage:
- rootflags=<comma-separated-array>
- rootflags=subvol=root,compress,ssd
FAQ, Known Issues and limitations
- Release specific known issues and workarounds are posted in changelog files.
- Check also the forum threads for posted fixes and workarounds.
- Why screen stays blank or other weird screen issues happen?
- Some hardware doesn't like the KMS activation, use radeon.modeset=0, i915.modeset=0 or nouveau.modeset=0 on boot prompt.
- dmraid/fakeraid might be broken on some boards, support is not perfect here.
- The reason is there are so many different hardware components out there. At the moment 1.0.0rc16 is included, with latest fedora patchset, development has been stopped.
- mdadm supports some isw and ddf fakeraid chipsets, but assembling during boot is deactivated in /etc/mdadm.conf!
- grub2 cannot detect correct bios boot order:
- It may happen that hd(x,x) entries are not correct, thus first reboot may not work.
- Reason: grub cannot detect bios boot order.
- Fix: Either change bios boot order or change menu.lst to correct entries after successful boot. This cannot be fixed it is a restriction in grub2!
- Why is parted used in setup routine, instead of cfdisk in msdos partitiontable mode?
- parted is the only linux partition program that can handle all type of things the setup routine offers.
- cfdisk cannot handle GPT/GUID nor it can allign partitions correct with 1MB spaces for 4k sector disks.
- cfdisk is a nice tool but is too limited to be the standard partitioner anymore.
- cfdisk is still included but has to be run in an other terminal.

Howto: Create image files
(Quick regeneration of installation media with latest available core packages)
Requirements
- x86_64 architecture
- ~ 3GB free space on disk
Create archboot chroots
# install archboot pacman -S archboot mkdir <x86_64_chroot> pacman --root "<x86_64_chroot>" -S base --noconfirm --noprogressbar mkdir <i686_chroot> linux32 pacman --root "<i686_chroot>" -S base --noconfirm --noprogressbar
- Enter archboot x86_64 container:
systemd-nspawn --capability=CAP_MKNOD -M $1-$(uname -m) -D <x86_64_chroot>
- Enter archboot i686 container:
linux32 systemd-nspawn --capability=CAP_MKNOD -M $1-$(uname -m) -D <i686_chroot>
Install archboot and update to latest packages
# install in both chroots archboot: pacman -S archboot # update in both chroots to latest available packages pacman -Syu
Generate images
# run in both chroots (needs quite some time ...) archboot-allinone.sh -t # put the generated tarballs in one directory and run (needs quite some time ...) archboot-allinone.sh -g
- Finished you get a bunch of images.
Have fun! tpowa (Archboot Developer)
