Will this replace the current sudo ?
The reality is that all programmers are insecure programmers. The ones arrogant enough to think they are not insecure are the most dangerous.
To be fair, I think the OpenBSD people have demonstrated they're pretty capable at writing decently secure software in C.
rsu, rsudo
surs, sudors (and then /etc/sudorsers as the cherry on top)
I don't know. But if its a drop-in replacement, which aims compatibility, then the same name seems OK. And for most use-cases, this will be a drop-in replacement. Except for obscure configs. But I think that's OK. If your goal is world domination, you aim for the low hanging fruit first.
