This would seem to be more reasonable defaults to me, and both can be increased if required by a particular user.<o:p></o:p></p><p class=MsoNormal><br>With a swap default maximum of 8GB, this would reduce our minimal install size from roughly 4GB + 0.8 * RAM to roughly a max of 13 GB.<o:p></o:p></p><p class=MsoNormal>In real figures, a server with 48GB RAM would require 13 GB of boot drive space versus the current 44 GB<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thoughts?<o:p></o:p></p><p class=MsoNormal>Deano<o:p></o:p></p></div></body></html>
