Set default hostname on form without specifying a username or logging in

[abcbarryn]

If I add ?hostname=foo to the URL the hostname does not populate in the webform unless I do ?hostname=foo&username=bar but then it automatically attempt to login once and fails because there is no password. I would like to be able to pass a default hostname but leave the username field blank and wait for the user to fill in the form before attempting to login.

I edited main.js and commented out these 3 lines and that seems to give me the exact behavior that I want...

//    if (!username) {
//      errors.push('Value of username is required.');
//    }
