I certainly trust HPA's example, but it is a far sight from the 'documented' procedure. If the pivot_root developers expect everyone in the world who depended previously on an implicit change_root to modify their procedures, they have the responsibility to see that the "better way" is understood. If HPA's example is adequate the documentation should be modified. E H. Peter Anvin wrote: > Richard B.
