I'm wanting to learn the possible sequence of PTFs. Base + PTF1 gives error + PTF2 gives good result.
Normal updates would be Base + PTF1 (without install) + PTF2 gives good result. Site with base finds out and wants to avoid PTF1 and install PTF2. But PTF2 can't install without PTF1? Creating PTF3 with 1 and 2 for base won't install on Base + PTF1?
