+# This should run in a DCL VM with an OK amount of cores (4/8 minimum),
+# 4G RAM, and storage of roughly 20G + 5G * #resulting_images.
+#
+# This is because there is the base system, a 'pristine chroot', and during the
+# build there can be 2 copies of the resulting system written to the system.
+# Since there are 4 combinations of images:
+#   {STABLE,RELEASE} x {dualstack, IPv6ONLY}
+#
+# That means we'll need to assign about 40G storage to be on the safe side.
