+# into git since it changes regularly.
+# It's code looks like this:
+# if [[ ! -e /a/bin/fai/fai-wrapper ]]; then
+# case $HOSTNAME in
+# tp) DEBIAN STRETCH VOL_STRETCH STRETCH_FREE;;
+# # add more multi-boot hostnames here
+# esac
+# fi
+#
+#
+# Each host defines following:
+# The base distro:
+# UBUNTU, DEBIAN
+#
+# The base disto version, which is also the basefile name if it exists:
+# STRETCH64, XENIAL64, BELENOS64, FLIDAS64
+#
+# 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.
