* 'lookup-unhashed' option of distribute should be 'auto' by default.Amar Tumballi2010-02-061-0/+3
| | | | | | | | | | | | | | * Added 'auto' option, older boolean options works as they used to. * This option should make 'create' rate faster, also handles self-healing of linkfile properly in case of scaling to more servers or filesystem is getting full.
