suda#nopass adds the flag --non-interactive (or rather its short form -n) to the call to sudo. So it could be called that: suda#noninteractive.

Or, since it introduces a risk to cause non-working setups, you could call it suda#forcenoninteractive

I wonder if we should change suda#nopass to force suda to give up if saving without a password doesn't work?

now we have the check if sudo true works, and then we try without a password, which removes much of the requirement for the current behavior of suda#nopass

[aarondill]

The only notable issue I could see with this approach would be using different values for suda#executable, where this would then mean that suda will always ask for a password if suda#nopass isn't set, and will never ask if suda#nopass is set.

this would eliminate support for commands that cache credentials, like sudo does; but our support for other values of suda#executable is extremely rudimentary anyways.

suda#noninteractive (or suda#non_interactive) sounds good to me.
