While you are at it... Could you or somebody else spend some work digging around, why Elizabeth Zwicky's torture test causes dump/restore so many trouble when it has to deal with very long file/pathnames ? I wrote this already to -current some days ago, maybe the message has been ignored among the others and because of 2.2.7 ... Elizabeth Zwicky's torture test program (a perl script creating many nasty files) found out, that dump is the best program for doing backup's because it could deal with every problem. She told me now, after seeing the test results for -current, that she can't understand how broken dump/restore now is. You can find the torture test script and a transscript of a session showing the trouble here: http://www.freebsd.org/~andreas/download/torture.pl http://www.freebsd.org/~andreas/download/typescript.freebsd-current-3.0-980720 File sizes: -rw-r--r-- 1 andreas andreas 12595 23 Jul 21:57 torture.pl -rw-r--r-- 1 andreas andreas 128528 23 Jul 21:57 typescript.freebsd-current-3.0-980720 Her results from 1991 you can find in this paper: http://reality.sgi.com/zwicky_neu/testdump.doc.htm -- Andreas Klemm http://www.FreeBSD.ORG/~andreas What gives you 90% more speed, for example, in kernel compilation ? http://www.FreeBSD.ORG/~fsmp/SMP/akgraph-a/graph1.html "NT = Not Today" (Maggie Biggs) ``powered by FreeBSD SMP''
