That's what everybody believes until he tries. The problem is how to detect whether the config is old or new. This might be hacked somehow for specific cases, but it's impossible to do in an acceptable way for a generic case. Note that compat 1.0->1.1 does not necessarily mean swconfig->DSA, so we have no general variable that will define which state we are in. There is a reason why nobody provided a DSA migration script (or even tried AFAIK). This horse is dead. (Doing -f without -n is a real world problem. They might pseudo-brick their devices. However, we have no better solution about that at the moment.) Best Adrian > ;-) > > Regards,
