Yes, the behavior currently is:

	If I can figure out "who", I'll set the EMAIL/attributes based on that.
	If not, it'll default to the "don't know" behavior that throws up the list

Ideally, I'd prefer the second option be:

	Force user to specify --author if a good default can't be determined

But there doesn't appear to be a way to do that.

Not really, since there are lots of servers, and lots of application/service accounts. Where filesystem acl'ing can be used reasonably, it is, making this moot, but it still boils down to example case of "I have a team of X people maintaining Y different applications, each on their own dedicated account". I'd just like a good mechanism to set defaults based on information other than what is in the home dir on the occasions that users log in directly to the app account, as opposed to doing updates offline on their own systems/to central repo/etc.
