| |
Until the kernel delete/add route code gets fixed so there are not duplicate routes necessitating duplicate deletes until they are finally gone, here is a patch to net-tools `route`. This will help administrators who have large numbers of machines and don't want to have to rewrite a lot of scripts.
This is against net-tools 1.47 Route 1.94
