Introduced by: (v213)
Fixed by (for current persistent journal): (v229)
Starting with 215 Debian no longer ships tmpfiles.d/systemd.conf, so the fixup upstream added as
afae249efa4774c6676738ac5de6aeb4daf4889f for persistent journals is not needed for the packaged
version. Anyone using a custom config needs to ensure proper permissions.
