Do we in Linux world do this routinely? I would not say routinely, but I would say crucially. The poster child for dump/restore is a machine with commercial software that is difficult to install or customize, especially one with an RDBMS system large enough to make dumping and restoring the data tables an onerous task. The usual workflow -- kickstart and puppet/ansible/etc -- doesn't work in that situation. -- Paul Heinlein heinlein at madboa.com 45°38' N, 122°6' W
