+Subject: lib/commit: Fix EBADF with GENERATE_SIZES option for commit
+
+Regression from previous tmpfile refactoring; unfortunately
+the `OSTREE_REPO_COMMIT_MODIFIER_FLAGS_GENERATE_SIZES` option
+only has coverage via gjs currently.
+
+Might expose it via the cmdline in a later option, but in the big picture the
+idea was that this data is better kept in static deltas.
+
+Bug: https://github.com/ostreedev/ostree/issues/1014
+Forwarded: https://github.com/ostreedev/ostree/pull/1016
