Ahh, multiple errors. I hadn't thought of that.

Could you use a Message() rather than an Error() which is shown to the
user post-transaction? We already have the enum types:
PK_MESSAGE_ENUM_NOTICE, PK_MESSAGE_ENUM_WARNING and
PK_MESSAGE_ENUM_DAEMON - do any of those fit or do we need to create

Sure, an error has to be fatal, i.e. the daemon has to call Finished()
shortly after Error() and certainly not call Error() multiple times.

Would Message() do what you wish?
