It would be nice to mention explicity in the documentation what happens if the property `sling.installer.multiversion=true` is toggled on an already existing instance. Good point! I think blocking this case, with the installer storing and refusing to change that setting after the first startup would be the safest option. was (Author: bdelacretaz): bq.
