I'm not sure UML would help you here. I think you'd be better trying to run Apache in a chrooted environment, PHP and PostgreSQL included. You don't need another kernel, but another set of libraries. BTW, I think UMLSIM (umlsim.sf.net) could help to play the "unplug-the-server" game. In theory you could rewrite the block subsystem to "fail", simulating a real disk failure and possible a system shutdown. I don't have time to do it myself right now however ... -- Alvaro Herrera (<alvherre[a]dcc.uchile.cl>) "Find a bug in a program, and fix it, and the program will work today.
