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
-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. Disks are grouped as ssd or hdd and
scripts from https://iankelling.org/git, and of course there are some
hostnames that are specific to my network.
+Before doing a fai install, you will need to populate a class file. I
+use one called 5-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.

+For flidas, when installing systemd, this error happens, and it's
+a superflous upstream bug based on reading the post install script:
+
+addgroup: The group `systemd-journal' already exists as a system group. Exiting.
+Operation failed: No such file or directory

+# TODO
+Change arch to archlike and to support arch and parabola

-License stuff:
The license for the project is GPLv2 or later, mostly because fai is and
I periodically merge the upstream example config, which contains small
scripts. Also, there is a modified encrypt.upstream, which is from the
iankelling.org / git / automated-distro-installer / blobdiff
