+# Prevents creation of an unexpected user
+# The redundant "distro" subkey is necessary in order to match exactly what is in
+# `/etc/cloud/cloud.cfg`, omitting it would result in the default user still being created
+# as this would be a "generic" `system_info` while the one in `/etc/cloud/cloud.cfg` would be
+# the Ubuntu specific.
+# See: https://github.com/ubuntu/WSL/issues/468
