Might I suggest in the future purning down what you're responding to, to just that blurb? At first read of your response I thought you were arguing against the ABI var itself (which didn't make a helluva lot of sense). Meanwhile, yes, using preserve lib there still has some issues- the reason I mentioned it possibly being held onto is that if we're talking about something like openssl, having your system be horked for the intervening period isn't a great thing thus it may be useful as an option at the least. > > This however breaks down > > a bit when the ABI change is in reverse of normal versioning. > How so?

That comment is in reference to if preserve-lib is still enabled for the rebuild. ~harring
