   1 PXE install w multi-boot, btrfs & Libreboot support
   2
   3 Some things are specific to my home network, and uses files with secrets
   4 that are not in this repo. I use this for bare metal and vms, and two
   5 scripts which can run post boot so I use them on vps distributed image
   6 as well.
   7
   8 Features people may find useful: installs encrypted trisquel, debian,
   9 ubuntu, arch, and parabola (archlike install is likely broken, I've only
  10 done pxe boots recently), in a multi-boot setup using multiple
  11 subvolumes of a single btrfs filesystem.  Utilizes multiple disks, with
  12 scripts to automatically decrypt on intentional reboots, but not after
  13 shutdown or power loss.
  14
  15 Normal install mode for fai is using pxe, but on a libreboot system,
  16 there is no pxe. The pxe in a normal computer is nonfree
  17 firmware. Alternatives to normal pxe that I've tried:
  18
  19 * libreboot + seabios + ipxe
  20
  21 * Use a live cd to call pxe-kexec, this is described later in this file.
  22
  23 * Use the fai autodiscover iso. This is more automated, so nicer.
  24
  25 * Use an install method above to setup a gnu/linux disk partition that
  26   coordinates with libreboot grub to acts like a pxe boot using
  27   kexec. The boot process takes a bit longer than normal pxe. This is
  28   the bootstrap partition in my scripts.
  29
  30 Things I haven't tried:
  31
  32 * The bios chip has enough room for an initrd. This could be setup to
  33   work like the partition I use to kexec, but it would be faster, and
  34   not require installing to disk.
  35
  36 The partititioning and filesystem script is at
  37 fai/config/hooks/partition.DEFAULT. Disks are grouped as ssd or hdd and
  38 raided in raid 1 or raid 0 per configuration. The base partitions are
  39 divided into boot, swap, and root, (only boot is unencrypted). There are
  40 scripts to resize those partitions post-provision and while the system
  41 is running.
  42
  43 People who use fai may find these things as useful examples: it uses
  44 dnsmasq (on a openwrt machine) for dhcp instead of the isc
  45 dhcp. fai-wrapper is a small script to use basic fai classes outside of
  46 fai. It does not use the fai partitioning tool, but the script is
  47 inspired from it and works outside of fai. It supports running a fai
  48 server on debian within android via Maru.
  49
  50 It also automates configuration of an openwrt router after manual
  51 initial installation.
  52
  53 After provisionining is done, I sync files using btrfs, or unison for
  54 vps, then automate further setup using a different set of scripts,
  55 https://iankelling.org/git/?p=distro-setup;a=tree.
  56
  57 My network is a wndr3700v2 router with openwrt on it and a few pcs/laptops.
  58
  59 Since fai requires a debian server as the fai server, there are also
  60 scripts to automate a debian install using pxe and preseeding, which can
  61 be done from any distro.
  62
  63 Some of the scripts have dependencies for some simple obvious utility
  64 scripts from https://iankelling.org/git, and of course there are some
  65 hostnames that are specific to my network.
  66
  67 Before doing a fai install, you will need to populate a class file.  I
  68 use one called 5-multi-boot, which you can see example of in
  69 fai/config/class/50-host-classes.

  73 All scripts meant to be used directly are listed here:
  74
  75
  76 # Scripts to setup the environment for the install
  77
  78 sudo fai-cd -g grub.cfg.autodiscover -f -A $BASEFILE_DIR/autodiscover.iso # create autodiscover cd
  79 mymk-basefile # Create basefiles for various distros
  80 archlike-pxe # Setup pxe boot server from an archlike base image
  81 fai-redep # Deploy fai configuration to host "faiserver"
  82 faiserver-uninstall # uninstall fai-server
  83 faiserver-setup # install fai-server on the current machine
  84 myfai-chboot # setup fai tftp and nfs. useful for doing pxe-kexec
  85 pxe-server # disable/enable pxe dhcp, tfp, and nfs. calls myfai-chboot
  86 wrt-setup  # setup my router in general: dhcp, dns, etc.
  87
  88
  89 # Script to do a distro install
  90
  91 faiserver-revm # using pxe & preseed, create a vm which is a fai server
  92 dsfull # install & post-install a new fai distro
  93 arch-init-remote # install arch after it's been booted into it's setup env
  94 fai-kexec # Kexec this or a remote machine using host faiserver
  95 live-kexec # fai kexec from upstream live cds, e.g. curl live-kexec|bash
  96
  97
  98 # Test scripts
  99
 100 arch-revm # test arch install on a fresh vm
 101 fai-revm  # test fai install on a fresh vm
 102
 103
 104 # Scripts to call after a distro install for various reasons
 105
 106 chboot # Set grub to boot into a different distro (installed earlier)
 107 install-chboot # reinstall chboot to /boot subvols, for chboot updates.
 108 eboot # reboot without automatic disk decryption
 109 fai-wrapper # use fai classes outside of fai. sourced, not called.
 110 faiserver-disable # Disable the fai nfs server exports
 111 fresize # resize swap or boot partitions in a host
 112
 113
 114 # Replacing a raid 10 disk
 115
 116 pxe-server -S HOST fai
 117 ssh root@HOST
 118 cat >p
 119 for x in /target/*; do umount $x; done
 120 PASSWORD HERE(ctrl-d ctrl-d)
 121 for d in /dev/disk/by-id/ata*part1; do cryptsetup luksOpen --key-file p $d crypt_dev_${d##*/}; done
 122 # btrfs replace disk # i forget the actual command
 123 x=(/dev/mapper/*part1); mount -o subvol=root_trisquelflidas $x /mnt
 124 mount -o subvol=boot_trisquelflidas /dev/sda3 /mnt/boot
 125 for x in dev proc sys; do mount -o bind /$x /mnt/$x; done
 126 chroot /mnt /bin/bash
 127 # replace disk in fstab
 128 # replace disk in /etc/crypttab
 129 update-grub
 130 update-initramfs -u
 131 mount /a

 133 exit
 134 reboot
 135
 136
 137 # Expected output in fai logs
 138
 139 For flidas, when installing systemd, this error happens, and it's
 140 a superflous upstream bug based on reading the post install script:
 141
 142 addgroup: The group `systemd-journal' already exists as a system group. Exiting.
 143 Operation failed: No such file or directory
 144
 145
 146 # TODO
 147 Change arch to archlike and to support arch and parabola
 148
 149
 150 # License
 151
 152 The license for the project is GPLv2 or later, mostly because fai is and
 153 I periodically merge the upstream example config, which contains small
 154 scripts. Also, there is a modified encrypt.upstream, which is from the
 155 cryptsetup package in arch, which is under the same license.
