--- Comment #19 from Andrew Macleod <amacleod at redhat dot com> --- So what kinds of changes trigger this? That patch added a new --param option. Will this happen every time a --param option is added? what about changing a param option? because I am about to tweak the options to --param=evrp-mode to add some additional debugging modes as well.
