+# 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, FLIDAS64X
+#
+# 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.
