There once was a large penguin rookery located on an island that was designated as K-2.2.18. The penguin population that lived there was large and plentiful due to the fact that it provided suitable protection and sustenance. Due to this the population had grown large and was starting to look for new territory to occupy. Lo and behold they discovered a substantially larger island known as K-2.4.0 which had a wealth of untapped resources that would allow the colony to expand in the future. Unfortunately, the distance between K-2.2.18 and K-2.4.0 was large and full of many unknown dangers (not the least of which were large killer whales looking for tasty penguins to snack on). Despite this, many of the penguin population decided that the risk and effort necessary to reach K-2.4.0 was acceptable because of the opportunities it provided. This divided the penguins into a number of groups: o Group #1 was composed of some of the elder penguins, who had made successful ocean crossings in the past. They traveled together in a flock so as to mitigate their danger. They arrived successfully with only minor injuries. o Group #2 was formed from mature and adolescent penguins. When they ventured forth they either swam in groups for protection or as individuals who counted on their own strengths (speed and cunning) to insure a successful journey. Despite this they still encountered dangerous schools of jellyfish that inflicted damage upon some of them. These penguins required some time to recuperate after completing their journey Group #3 was made up of fledging penguins, who having seen others make the journey, decided they could do so as well. They launched from shore with a plan that consisted of nothing more than a dream of Island K-2.4.0 for they were unexperienced in such endeavors. Many of them became lost during the journey or were eaten by killer whales hunting for the inexperienced. Of the remaining penguins, the majority turned back to K-2.2.18. A few of the original group did make it K-2.4.0 and spent much time recuperating from the exhausting swim and the mental trauma from having seen their friends eaten. Group #4 was all the other penguins left on K-2.2.18. These penguins waited a number of months till the ocean calmed down and the killer whales migrated to warmer waters. A this point the majority of them departed from K-2.2.18 for K-2.4.0 with friendly schools of dolphins to guide them (designated Pod-RedHat, Pod-SuSe, Pod-Sistina, etc...). They arrived without incident on K-2.4.0. Those left on K-2.2.18 maintained the rookery and lived happy ever after. The moral of the story -- If you are a Group #3 penguin don't expect much sympathy from your wiser or more cautious brethren when you get eaten. --- Michael Declerck, declerck@sistina.com +1.510.823.7991
