Seriously, the default options to ssh-keygen should be all anybody needs. If you need to pass arguments to increase the security of the generated key, then the software has completely failed its purpose. Passing arguments should only be for falling back on less secure options, if there is some limiting factor for a particular deployment.
There is absolutely no reason to pass arguments to ssh-keygen. If it is actually deemed necessary to do so, then that package's installation is inexcusably broken.
