This is useful to identify log messages with metadata from the images they run on. Look for ID/VERSION_ID/IMAGE_ID/IMAGE_VERSION/BUILD_ID, with a SYSEXT_ prefix if we are looking at an extension, and append via LogExtraFields= as respectively PORTABLE_NAME_AND_VERSION= in case of a single image. In case of extensions, append as PORTABLE_ROOT_NAME_AND_VERSION= for the base and one PORTABLE_EXTENSION_AND_VERSION= for each extension. Example with a base and two extensions, with the unit coming from the first extension: [Service] RootImage=/home/bluca/git/systemd/base.raw Environment=PORTABLE=app0.raw BindReadOnlyPaths=/etc/os-release:/run/host/os-release LogExtraFields=PORTABLE=app0.raw Environment=PORTABLE_ROOT=base.raw LogExtraFields=PORTABLE_ROOT=base.raw LogExtraFields=PORTABLE_ROOT_NAME_AND_VERSION=debian_10 ExtensionImages=/home/bluca/git/systemd/app0.raw LogExtraFields=PORTABLE_EXTENSION=app0.raw LogExtraFields=PORTABLE_EXTENSION_NAME_AND_VERSION=app_0 ExtensionImages=/home/bluca/git/systemd/app1.raw LogExtraFields=PORTABLE_EXTENSION=app1.raw LogExtraFields=PORTABLE_EXTENSION_NAME_AND_VERSION=app_1
