Scenario

• We're stuck with a machine you want to reinstall remotely.
• Our Intel AMT won't "remote desktop", for whatever reason (Eg. perhaps you have no monitor attached, and haven't got around to buying a dummy display adapter)
• We've previously configured Intel AMT serial-over-lan in MEB to work with grub early boot
• We have a way to access this serial console remotely (Eg. https://github.com/Ylianst/MeshCentral - npm install meshcentral; node node_modules/meshcentral and whatever networking shenanigans it takes to make that work)
• Our system previously already had GRUB configured to work over serial:
  • For me that meant /etc/default/grub with GRUB_TERMINAL_INPUT, GRUB_TERMINAL_OUTPUT, GRUB_SERIAL_COMMAND set correctly
  • See https://www.gnu.org/software/grub/manual/grub/html_node/Simple-configuration.html
  • For me GRUB_SERIAL_COMMAND was serial --unit=4 --speed=115200 --word=8 --parity=no --stop=1 --port=pci,00:16.3
• Why --port=pci,00:16.3? That's the (shortened) PCI bus addr

# Thanks to http://ubuntuforums.org/showthread.php?t=1411273 for inspiration..
# But what a disgusting nasty hack! This prevents partman from running (and
# mounts /target, creates /target/etc/fstab). d-i just can't cope with
# installation to partitionless block device... which is disappointing,
# because partitions are pointless for pvlinux guests.
#
# The hack works by ... wait for it... spawning a little while/sleep 1 script,
# waits for the partman-base.postinst file to appear (the preseed/earl_command
# hook is too early, and the partman/early_command is too late). Once it
# appears we replace this with a bit more script which does what we wanted

# Although Dockerfiles allow you to ADD a directory, this isn't cacheable.
# Instead, maintain a tarball which allows you to ADD a host directory as a file
