Hooray! I've been looking for this information for ages and didn't know this was the question to ask. What this does is anable me to run multiuser Windows games under Wine! Not multi at the same time, but each user saves. If the game keeps all the saves in one file, or even has a file where it keeps *some* of the per-user information, the question of ownership arises. If it's save using the user's uid, no one else will be able. But if we install the entire game with a gamer group ID and a user ID that no one uses, enable writing in the proper directories (if necessary, all of them) then everything will just work, because the gamer-group ID will be used for all the files! > > yours > Albert -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
