This requires at least some development tools, +pacman and some base system to be cross-compiled. + +We also want basic network connetivity, so we can use +the i486 VMs or real i486 as build slaves. Also, having +a minimal bootable ISO for the i486 system (or even a +set of floppies or PXE boot via a boot floppy would +be very useful). We cannot have kernel modules in a +ramdisk or systemd for this basic system because they +interfere heavily with memory constains on a 486! So, +we build up to an openssh server. + +On top, the full Archlinux i486 universe can then be +built (either with a i486 chroot or via a i486 master/ +distcc slaves setup or a distributed i486 cluster setup). + +There is another caveat: we are patching the PKGBUILDs +to do proper cross-compilation (--with-host, --with-target). +Still we try to stay close to the original PKGBUILDs. + +references +---------- + +https://archlinuxarm.org/wiki/Distcc_Cross-Compiling +https://wiki.archlinux.org/index.php/Cross-compiling_tools_package_guidelines +http://mgalgs.github.io/2011/12/08/creating-arch-linux-packages-by-hand.html +http://clfs.org/view/svn/ppc/chroot/before-chroot.html +http://www.linuxfromscratch.org/clfs/ +https://www.dotslashlinux.com/2017/04/29/booting-the-linux-kernel-without-an-initrd-initramfs/ +https://rubenerd.com/sata-on-qemu/ +https://archlinuxarm.org/forum/viewtopic.php?f=57&t=6163 +https://dustymabe.com/2012/12/15/mounting-a-partition-within-a-disk-image/ +http://preshing.com/20141119/how-to-build-a-gcc-cross-compiler/ +http://wiki.osdev.org/GCC_Cross-Compiler +http://www.linuxfromscratch.org/lfs/view/6.2/chapter05/adjusting.html +https://wiki.debian.org/FakeRoot +https://archlinuxarm.org/forum/viewtopic.php?f=57&t=6163 +https://www.phenix.bnl.gov/~purschke/RescueCD/ +https://github.com/ivandavidov/minimal-linux-script +https://askubuntu.com/questions/109413/how-do-i-use-overlayfs +https://how-to-build-for-arm.wikispaces.com/ +https://arsv.github.io/perl-cross/ +http://www.ibb.net/~anne/keyboard.html + +recipes +------- + +######### +# PHASE 0 +######### + +# Prepare the host.
