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, debian,
ubuntu, and arch (havne't done recently, probably a bit broken), in a
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. What
+I've done instead:
+
+* 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
+ acts like a pxe boot using kexec, but it takes a bit longer. This is
+ the bootstrap partition in my scripts.
+
+Things I haven't tried:
+
+* There is iPXE, which requires standard bios functions, which can be
+ provided by seabios, which can be a libreboot payload.
+
+* 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. Disks are grouped as ssd or hdd and
raided in raid 1 or raid 0 per configuration. The base partitions are
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:
