Yes, I think that's a good option. So to set the default to oak_tar the
sling.properties file should contain a line similar to the following:

sling.run.mode.install.options=jackrabbit,oak|oak_tar,oak_mongo

That indicates that run mode "jackrabbit" (default) or "oak" must be
active and "oak_tar" or "oak_mongo" must also be active. Is it a
problem if "oak_tar" is active for "jackrabbit" deployments?

Carsten, I believe you know this mechanism best. Is it possible to
have run modes depend on the presence of other run modes?

Regards
Julian
