# For multi-boot system.
# We check that we aren't in a pxe boot environment.
# There is probably a better way to do this.
# We check the reverse condition in 51-multi-boot,
# and set what os we are installing, but don't check it
# into git since it changes regularly.

#
#
# Each host defines following:
# The base distro:
# UBUNTU, DEBIAN
#
# The base disto version, only use so far is the basefile name if it exists.
# Debian stable basefile gets built by faisetup and gets used otherwise.
# With X suffix, means it has gone through the dirinstall process and has eXtra
# things installed, to speed up installation.
# STRETCH64, XENIAL64, BELENOS64, FLIDAS64, FLIDAS64BIG
#
# The distro subvol name, we can add as many of these as we want:
# VOL_TESTING, VOL_STRETCH, VOL_XENIAL, VOL_BELENOS, VOL_FLIDAS, VOL_STRETCH_BOOTSTRAP
# Using VOL_STRETCH_BOOTSTRAP sets up the install to act like a pxe rom if
# grub sets a specific var.
#
# The apt sources files we want,
# STRETCH_FREE, STRETCH_NONFREE, TESTING_FREE, TESTING_NONFREE,
# XENIAL_FREE, FLIDAS, BELENOS, STRETCH_LINODE.
#
# It's all a little redundant in some cases, but it keeps things
# simpler. Belenos is broken right now, planning to remove it once
# flidas is released and rms has upgraded.
#
#
# Other notable classes:
#
# INSTALL: for autodiscover iso, this is needed. We could also add it to
# the autodiscover grub, but then we have to burn a new iso if we want a
# non-install one. It sets the class for the corresponding INSTALL.var,
# which sets FAI_ACTION=INSTALL. I'm not sure if this variable overrides
# FAI_ACTION outside of autodiscover, todo: test it out, if it doesn't,
# make install be default in 51-multi-boot, and disable it if needed.
#
# DESKTOP: install a bunch of extra packages. For creating X suffix
# basefiles. See README.
#
# REPARTITION: we try to reuse partitions/filesystems to install a new
# os into a multi-os system, if we see some basic hueristics, like the
# right amount of them. This overrides that.
#
# PARTITION_PROMPT: If we don't see partitions to reuuse, prompt
# to make sure we really want to repartition and use a completely
# fresh install. I use this in case our repartition check has
# a bug in it, or I accidentally set REPARTITION.
#
# ROTATIONAL: in a system with ssd and hdd, install to the hdd
# instead of the default ssd.
#
# RAID0: Use raid 0 even if there are >= 4 disks with boot partititions.
#
#
# Code in 51-multi-boot, with reasonable combinations of above
# uncommented for easier editing, and runs as a noop until
# we replace _ with host names.
