Requirements
------------

pacman -S archiso qemu syslinux darkhttpd

ArchISO and optional local cache
--------------------------------

We build a live Arch boot CD.

export http_proxy=http://192.168.1.12:3128
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 take quite a while

./build.sh -v build single

cd ..

We mount it and make it accessible over a webserver:

mkdir archiso
mount -o loop,ro archlive/out/archlinux-2013.05.16-dual.iso archiso
darkhttpd . --port 8080 &

We can also make available the packages on this webserver:

mkdir -p {core,extra,community}/os/x86_64/
repo-add core/os/x86_64/core.db.tar.gz core/os/x86_64/*
tar zcvfT extra/os/x86_64/extra.db.tar.gz /dev/null
ln -s extra.db.tar.gz extra/os/x86_64/extra.db
tar zcvfT community/os/x86_64/community.db.tar.gz /dev/null
ln -s community.db.tar.gz community/os/x86_64/community.db

TFTP root
--------

Copy PXE bootstrap files to a TFTP root:

mkdir -p tftproot/boot/x86_64
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/pxelinux.0 tftproot

Custom software from AUR
------------------------

Build the following packages from AUR:

qdbm-1.8.78-1-x86_64.pkg.tar.xz
cfengine-3.4.4-2-x86_64.pkg.tar.xz

Put them into a local repository 'aba':

mkdir -p aba/os/x86_64/
repo-add aba/os/x86_64/aba.db.tar.gz aba/os/x86_64/*

Install Archlinux
-----------------

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 -hda arch.img -net nic \
	-net user,tftp=$PWD/tftproot,bootfile=pxelinux.0 \
	-m 386 -display curses \
	-machine accel=kvm -redir tcp:222::22 \
	-boot n

# remote install (manually), then follow docu
# (this gives a rough idea of what should be automatized)
passwd
systemctl start sshd

# 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

Running the system
------------------

qemu-system-x86_64 -hda arch.img -net nic \
	-net user \
	-m 386 -display curses \
	-machine accel=kvm -redir tcp:222::22
