PXE install w multi-boot, btrfs & Libreboot support
Some things are specific to my home network, and uses files with secrets
-that are not in this repo. Uses pxe or pxe-kexec (on libreboot, I have
-not added a pxe rom, I use a minimal debian stable subvolume which acts
-like a pxe rom). I use this for bare metal and vms, and two scripts
-which can run post boot so I use them on vps distributed image as well.
-
-Features people may find useful: installs encrypted trisquel belenos, ,
-debian jessie, debian stretch, ubuntu 16.04, and arch (havne't done
-recently, probably a bit broken), in a multi-boot setup using multiple
+that are not in this repo. I use this for bare metal and vms, and two
+scripts which can run post boot so I use them on vps distributed image
+as well.

+Features people may find useful: installs encrypted trisquel, debian,
+ubuntu, arch, and parabola (archlike install is likely broken, I've only
+done pxe boots recently), in a multi-boot setup using multiple
subvolumes of a single btrfs filesystem. Utilizes multiple disks, with
scripts to automatically decrypt on intentional reboots, but not after
shutdown or power loss.
+Normal install mode for fai is using pxe, but on a libreboot system,
+there is no pxe. The pxe in a normal computer is nonfree
+firmware. Alternatives to normal pxe that I've tried:
+
+* libreboot + seabios + ipxe
+
+* Use a live cd to call pxe-kexec, this is described later in this file.
+
+* Use the fai autodiscover iso. This is more automated, so nicer.
+
+* Use an install method above to setup a gnu/linux disk partition that
+ coordinates with libreboot grub to acts like a pxe boot using
+ kexec. The boot process takes a bit longer than normal pxe. This is
+ the bootstrap partition in my scripts.
+
+Things I haven't tried:
+
+* The bios chip has enough room for an initrd. This could be setup to
+ work like the partition I use to kexec, but it would be faster, and
+ not require installing to disk.

The partititioning and filesystem script is at
-fai/config/hooks/partition.DEFAULT. Other debian based distros at least
-as new as ubuntu 14.04 should work fine, and I'm planning to add Fedora
-support. Disks are grouped as ssd or hdd and raided in raid 1 or raid 0
-per configuration. The base partitions are divided into boot, swap, and
-root, (only boot is unencrypted). There are scripts to resize those
-partitions post-provision and while the system is running.

People who use fai may find these things as useful examples: it uses
dnsmasq (on a openwrt machine) for dhcp instead of the isc
scripts from https://iankelling.org/git, and of course there are some
hostnames that are specific to my network.
-All scripts meant to be used directly are listed here:
+# Per-host/install configuration
+
+Before doing a fai install, you will need to populate a class file. I
+use one called 51-multi-boot, which you can see example of in
+fai/config/class/50-host-classes.
+
+
+
+Before doing a fai install, you will need to populate /q/root/luks and
+/q/root/shadow, see their references. You might also want to copy
+existing /etc/ssh/*host* to
+/p/c/machine_specific/HOST/filesystem/etc/ssh
+
+host-* luks keyfiles generated like:
+head -c 2048 /dev/urandom | od | s dd of=/q/root/luks/host-demohost
+
+Configuration of which luks key to use is in
+fai/config/hooks/partition.DEFAULT
-# Scripts to setup the environment for the install
+Configuration of which (if any) shadow file to use is in
+fai/config/distro-install-common/end
+and which shadow file / luks file(s) to copy into the new machine depends
+on fai-redep arguments.
-arch-pxe # Setup arch pxe boot server from an arch base image
+# Scripts (meant to be used directly):
+
+
+# Setup the environment for the install
+
+# create tiny autodiscover cd
+# todo: with fai-revm at least, this complains about missing vmlinuz. need to fix this.
+fai-redep && sudo fai-cd -g $PWD/grub.cfg.autodiscover -f -A $BASEFILE_DIR/autodiscover.iso
+# create normal fai cd (replace TARGET_HOSTNAME)
+fai-redep -t TARGET_HOSTNAME && sudo fai-cd -M -g $PWD/grub.cfg.netinst-noreboot -f $BASEFILE_DIR/netinst.iso
+# note, may need to set hostname, depending on config,
+# and some other things for environment not on your lan

+Similar to python, linux-image-amd64 is the debian package name

+* create 2 disks, installer (3000 mb, raw), boot (remaining, raw)
+* create 2 profiles w direct boot, no helpers:
+ * installer (sda=boot, sdb=installer, boot dev=sdb)
+ * boot (sda=boot)
+* Boot into rescue mode, ssh in with lish,
+ curl url_to_some_fai_cd_created_image | dd of=/dev/sda
+ poweroff
+* boot into installer.
+* Lish shows console, at the end of install, it gives prompt because
+ logs failed to save remotely, check the logs, then reboot into boot
+ profile if all is well. If that doesn't happen, turn off lassie in
+ settings.

+# ubuntu notes
+
+For someone who really needed ubuntu on host tp, otherwise they would
+end up on a non-gnu os, and I didn't want to figure out how to get all
+the default software installed, I did the following:

+# install etiona
+cd /b/fai
+# set 51-multi-boot to set classes outside of fai-wrapper conditional, including NOWIPE
+. fai-wrapper
