+#
+# Each host defines following:
+# The base distro:
+# UBUNTU or nothing. DEBIAN is always defined as a base.
+#
+# 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, BUSTER64, BULLSEYE64, BOOKWORM64
+# FLIDAS64, FLIDAS64BIG, ETIONA64, NABIA64
+# XENIAL64, BIONIC64, FOCAL64,
+#
+# The distro subvol name, we can add as many of these as we want:
+# VOL_TESTING, VOL_STRETCH, VOL_BUSTER, VOL_BULLSEYE, VOL_BOOKWORM
+# VOL_FLIDAS, VOL_ETIONA, VOL_NABIA
+# VOL_XENIAL, VOL_BIONIC VOL_FOCAL
+# VOL_BUSTER_BOOTSTRAP.
+# Using VOL_BUSTER_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,
+# BUSTER_FREE, BUSTER_NONFREE,
+# BULLSEYE_FREE, BULLSEYE_NONFREE
+# BOOKWORM_FREE, BOOKWORM_NONFREE
+# TESTING_FREE, TESTING_NONFREE,
+# XENIAL_FREE, BIONIC, FOCAL, FLIDAS, ETIONA, NABIA, STRETCH_LINODE.
+#
+# It's all a little redundant in some cases, but it keeps things
+# simpler.
+#
+#
+# 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.
+#
+# REROOTFS: Don't reuse the root filesystem, even if we normally would
+#
+# NOWIPE: use existing subvolumes if they exist
+#
+# 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 partitions.
+#
+# LINODE: For running a vm on linode, especially one created with fai-cd.
+#
+# IANK / FSF: general setup of my machine vs FSF machines
+# NABIA_EXTRA: extra repos for NABIA from other distros
