K 10 svn:author V 5 dougb K 8 svn:date V 27 2005-12-20T20:36:48.000000Z K 7 svn:log V 378 Brooks pointed out a potential problem with disabling the X cleaning by default, so add a new knob that is on by default, and check that knob in start_precmd so that it can run even if cleaning /tmp is not enabled. This has the advantage of not violating POLA, while still allowing the user to disable this behavior if they wish (for example on a server that will never run X). END
