In theory the olb.path directive is declared as deprecated in the documentation, and will stop working with the next release. At some point it will be upgraded in Alien as well... The same consideration applies to oss.path, oss.nocheck and oss.nodread. Imho you should remove the deprecated stuff, and then put in the export directives that you need, without forgetting to set the 'mig' flag for each subdir that you want to be migratable. Btw, if you attach the current config file, I'll try to have a look at it asap.
