This week, we:

• got 11,570 messages from 275 different IP addresses.
• handled 20,679 sessions from 1,692 different IP addresses.
• received 186,687 connections from at least 62,023 different IPaddresses.
• hit a highwater of 10 connections being checked at once.

Well, so much for the trend of decreasing volume; all of these are upnoticeably from last week . The per day tablesuggests that

There are a number of situations where you might want to do somethinglike build a stock kernel.org kernel withthe same configuration options as a normal Fedora RPM-installed kernel.Alternately, you want to compile a Fedora kernel with a slightlydifferent set of options. These days, how to do this is slightly lessthan obvious and there is a gotcha or two.

With network installs,well, it depends; there is very little commonality on how you get tothe 'follow the installer's directions' stage.

This is the real attraction of virtual DVD-ROMs : likethe old math joke, they reduce
