I'm not sure I would call two and a half minutes on first boot all that fast. (That's on the sparc box I installed today, which has been slimmed down a bit - one of my key minimization priorities now is not to reduce the amount of software delivered but the number of manifests, as that's a limiting factor. An opteron box is quicker, as you would expect, but you're still looking at a minute which is appreciable. And there's several seconds every boot as well.) I'm sure glad it's better than it was, but that's still getting close to 1s per manifest. How many more might we add? -- -Peter Tribble http://www.petertribble.co.uk/ - http://ptribble.blogspot.com/ _______________________________________________ pkg-discuss mailing list pkg-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/pkg-discuss
