Trick it. Install the files you don't want to back up, only. Back up the stuff you want to back up using tar. Call that your "level 0". Create a bogus dumpdates entry for this level 0. Install the rest of the stuff. Do a level 1. From now on, only do level 1s and above. Treat the level 1s as level 0s. -- Peter da Silva (NIC: PJD2) `-_-' Network Management Technology Incorporated 'U` 1601 Industrial Blvd. Sugar Land, TX 77478 USA +1 713 274 5180 "Har du kramat din varg idag?"
