+# This file contains the image definitions for the bootc
+# "distro". bootc is special in the sense that a lot of what would
+# normally be in the YAML is introspected from the bootc container. So
+# the definitions are a lot smaller. They are used by
+# pkg/distro/bootc.
+#
+# Note that we want to explore to use the "generic" distro for
+# bootc as well but that is still some way off.
