+= Setting an Alternative Directory for Remote Execution Jobs in Pull Mode
+
+By default, {Project} uses the `/run` directory on hosts for remote execution jobs in pull mode.
+If the `/run` directory on your host is mounted with the `noexec` flag, {Project} cannot execute remote execution job scripts in this directory.
+You can use the `yggdrasild` service to set an alternative directory for executing remote execution jobs in pull mode.
+
+.Procedure
+On your host, perform these steps:
+
+. Create a new directory:
++
+[options="nowrap", subs="+quotes,verbatim,attributes"]
+----
+# mkdir _/My_Remote_Working_Directory_
+----
+. Access the `yggdrasild` service configuration:
++
+[options="nowrap", subs="+quotes,verbatim,attributes"]
+----
+# systemctl edit yggdrasild
+----
+. Specify the alternative directory by adding the following line to the configuration:
++
+[options="nowrap", subs="+quotes,verbatim,attributes"]
+----
+Environment=FOREMAN_YGG_WORKER_WORKDIR=_/My_Remote_Working_Directory_
+----
+. Restart the `yggdrasild` service:
++
+[options="nowrap", subs="+quotes,verbatim,attributes"]
+----
+# systemctl restart yggdrasild
