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

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