 * `OSTREE_UPDATE_SUMMARY` - Set this to '1' to update summary of OSTree repository on each commit. '0' by default.
 * `OSTREE_DEPLOY_DEVICETREE` - Set this to '1' to include devicetree(s) to boot
 * `GARAGE_SIGN_AUTOVERSION` - Set this to '1' to automatically fetch the last version of the garage tools installed by the aktualizr-native. Otherwise use the fixed version specified in the recipe.
+* `GARAGE_TARGET_URL` - sets the `--url` parameter of `garage-sign targets add`, which sets a custom URL for the Image repository targets.
+* `GARAGE_TARGET_EXPIRES` - sets the `--expires` parameter of `garage-sign targets sign`. Format is a UTC instant such as '2018-01-01T00:01:00Z'.
+* `GARAGE_TARGET_EXPIRE_AFTER` - sets the `--expire-after` parameter of `garage-sign targets sign`. Format is in years, months, and days (each optional, but in that order), such as '1Y3M5D'.
 * `INITRAMFS_IMAGE` - initramfs/initrd image that is used as a proxy while booting into OSTree deployment. Do not change this setting unless you are sure that your initramfs can serve as such a proxy.
 * `SOTA_PACKED_CREDENTIALS` - when set, your ostree commit will be pushed to a remote repo as a bitbake step. This should be the path to a zipped credentials file in https://github.com/advancedtelematic/aktualizr/blob/master/docs/credentials.adoc[the format accepted by garage-push].
 * `SOTA_DEPLOY_CREDENTIALS` - when set to '1' (default value), deploys credentials to the built image. Override it in `local.conf` to built a generic image that can be provisioned manually after the build.

+=== garage-sign configuration
+
+The https://github.com/advancedtelematic/ota-tuf/tree/master/cli[garage-sign] tool can be configured with variables described in the <<sota-related-variables-in-localconf,SOTA-related variables in local.conf>> section.
+
+Of particular importance is controlling the expiration of the Targets metadata signed with garage-sign. This is described in detail in the https://docs.ota.here.com/ota-client/dev/metadata-expiry.html[OTA Connect documentation]. To set a manual expiration date, you can use either of the variables `GARAGE_TARGET_EXPIRES` or `GARAGE_TARGET_EXPIRE_AFTER`. Both cannot be supplied simultaneously. If neither are provided, a default of one month will be used.
