Requirements
------------
pacman -S archiso qemu syslinux darkhttpd xmlstarlet
or
pacman -S libvirt qemu qemu-arch-extra xmlstarlet
ArchISO and optional local cache
--------------------------------
# We build a live Arch boot CD.
mkdir archlive
cp -r /usr/share/archiso/configs/releng/* archlive/.
cd archlive
# always had problem with keys, switch of signing (not good, I know)
sed -i 's/^SigLevel.*/SigLevel = Never/g' pacman.conf
# build the live CDs, this takes quite a while
./build.sh -v build single
cd ..
# We mount it and make it accessible over the 'darkhttpd' webserver:
mkdir archiso
mount -o loop,ro archlive/out/archlinux-2016.02.06-dual.iso archiso
darkhttpd . --port 8080 &
# copy packages from host system (there is no need to build a full-fledged
# mirror now, basic packages should all exist on the host)
./copy_local_packages.sh
TFTP root (for PXE boot)
---------
Copy PXE bootstrap files to a TFTP root:
cp archiso/arch/boot/x86_64/vmlinuz tftproot/boot/x86_64/
cp archiso/arch/boot/x86_64/archiso.img tftproot/boot/x86_64/
cp /usr/lib/syslinux/bios/pxelinux.0 tftproot
cp /usr/lib/syslinux/bios/ldlinux.c32 tftproot
Local kernel and RAMdisk (for libvirt direct kernel boot)
------------------------
cp archiso/arch/boot/x86_64/vmlinuz .
cp archiso/arch/boot/x86_64/archiso.img .
Custom software from AUR
------------------------
Build the following packages from AUR:
useradd -g users build
rm -rf INSTALL
mkdir INSTALL
cd INSTALL
yaourt -G cfengine
chown -R build:users cfengine
cd cfengine
su build -c 'makepkg -f'
cd ..
cd ..
Put them into a local repository 'myrepo':
rm -rf myrepo
mkdir -p myrepo/os/x86_64/
cp INSTALL/*/*pkg.tar.xz myrepo/os/x86_64/.
repo-add myrepo/os/x86_64/myrepo.db.tar.gz myrepo/os/x86_64/*
Install Archlinux (PXE and qemu directly)
-----------------
Create a Qemu image with Archlinux (automatically). The main
work is done by the 'archauto.sh' script which is given to
the archiso kernel as script to execute after auto-login:
qemu-img create arch.img 4G
qemu-system-x86_64 -drive file=arch.img,index=0,media=disk,format=raw -net nic \
-net user,tftp=$PWD/tftproot,bootfile=pxelinux.0 \
-m 512 \
-machine accel=kvm -redir tcp:222::22 \
-nographic -serial mon:stdio |& tee log
Install Archlinux (libvirtd and virt-install)
-----------------
There are quite some steps here, so they are wrapped into a shell script:
./createvm.sh
TODOs
-----
# remote install (manually), then follow docu
# (this gives a rough idea of what should be automatized)
#passwd
#systemctl start sshd
#sed -i 's/#PermitRootLogin prohibit-password/PermitRootLogin yes/g' /etc/ssh/sshd_config
# automatic installation frameworks for ArchLinux
# - AIF
# - ArchBlocks
# - ArchBang
# - backpac: snapshots, not really the cfengine philosophy
# load them after boot of base system or customize the installation medium?
# EFI, later
# wget 'http://wiki.qemu.org/download/efi-bios.tar.bz2'
# qemu with efi
# efi partition etc
# manual minimal installation or "what's needed in a CFengine bootstrap
# script"?
# - boot loader
# - grub2
# - virtio ramdisk hooks
# - partitioning
# - sgdisk scripting (ArchBlocks does it nicely)
# - RAID, LVM, LUKS and friends
# - size, swap, filesystem, chunking
# - file system layout
# via cfengine
# packages net-tools gdisk
