There is a -t <secs> option to the boot command. It seems however that there is no possibility to select a specfic entry beforehand.

The barebox environment is a directory tree rather than a list of variables, so there is no way to load a text file as environment. There is the loadenv command which takes the path to an environment image as argument. You can generate such an image on the host with the bareboxenv tool and then load it under barebox with loadenv.
