+Subject: [PATCH] Fix IMDS token requests for managed identities
+
+This was broken by a035ee5f9416ef9188533de40b4ab1c37fb7c0af, which
+accidentally constructed the IMDS URL with a double slash at the start
+of the path. This is not properly routed on the server side, leading to
+a 404 error with some very misleading XML.
