Ah cool! I looked for something like this on a remote ubuntu system but failed to figure it out by myself. Do you also have the other archs with it ?
Yes, they come with many architectures.

Great. And without sudo you should see two of them fail. I intend to implement geteuid() and condition their result to it, that will be sufficient for most cases. I'd rather avoid seeing users run test programs under sudo actually, since they're run on the local system :-/
I see.
