тут важен билд. на версию пофигу, я давно уже это понял и не использую ее нигде.
главное понять, как оно ветвится

да, если инсталлеры засовать в iso, то их можно положить рядом с патчами. да и распакованные инсталлеры в общем то тоже можно. наверное так и надо сделать. просто у меня исторически собирались только патчи, а инсталлеры вот совсем недавно. скопилось чото

от 2.х.beta видимо не все патчи. у меня:
