+Add a value (e.g. env=*value*) to the container. Can be used multiple times.
+If the value already exists in the container, it is overridden.
+To remove an environment variable from the container, use the `--unsetenv`
+option.
+
+Note that the env updates only affect the main container process after
+the next start.
