I hate to say it Con, but this one seems to have broken the amanda-tar symbiosis. I haven't tried a plain 21-rc3, so the problem may exist there, and in fact it did for 21-rc1, but I don't recall if it was true for -rc2. But I will have a plain 21-rc3 running by tomorrow nights amanda run to test. What happens is that when amanda tells tar to do a level 1 or 2, tar still thinks its doing a level 0. The net result is that the tape is filled completely and amanda does an EOT exit in about 10 of my 42 dle's. This is tar-1.15-1 for fedora core 6. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
