Gang, I suspect that my position has been expressed adequately. Further discussion might become divisive, but a decision that incurs the overhead of performance or a rebuild on the default user base seems wrong (JUST MY OPINION.) It took ALOT of WORK (person years) to make FreeBSD perform as well as it does. BOTH the add-on crew and the general user base can have the performance and feature set without rebuilding, but the decision was apparently made to impose the cost of performance or rebuild and binary maintenance on the default user base. It makes more sense to have appropriately upgraded the system (by the NSS project) to avoid the performance hit by others and also provide the feature set. Apparently (I haven't fully analysed this) implementing the dlopen stuff for non-dynamic programs would have helped to mitigate this issue. (It might have put more burden on the NSS/PAM/whatever addon projects, but those are indeed addons that shouldn't take ANYTHING away from the rest of the project.) I am suggesting that the NSS crew and those who are concerned about performance can BOTH have the results that they wish for. 'All or nothing' creates divisiveness, and in these discussions it is TOO EASY to fall into that trap. I am not suggesting the loss of the new NSS stuff, but also suggest that ANY loss of performance when it can be avoided, is unwise. My opinion is known, and hopefully the loss of hard earned performance with person-years of work won't happen as time goes on. A little loss isn't that bad, but how much loss is too much loss (esp when not necessary?) <EOT> John
