 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
-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.
