OK, maximum 1 update per puppet run at the beginning of the run is exactly what Nigel's two lines in [note 6](#note-6) accomplish, which seems OK to me but other comments here said that was too frequent. ---------------------------------------- Feature #3537: It should be possible to trigger (exec) resources with require https://projects.puppetlabs.com/issues/3537#change-91557 * Author: Kjetil Torgrim Homme * Status: Needs Decision * Priority: Normal * Assignee: eric sorenson * Category: metaparameters * Target version: * Affected Puppet version: 0.25.4 * Keywords: * Branch: ---------------------------------------- When an Exec has conditions associated with it (unless, creates, onlyif), it can be useful to be state prerequisites which are only run when the exec itself is run. Consider this simple example:: <pre> exec { "prereq": command => "/bin/echo prereq", refreshonly => true } exec { "main": command => "/bin/echo main", onlyif => "/bin/grep foobar /etc/issue", require => Exec["prereq"] } </pre> Here, the refreshonly will cause "prereq" to never run, since a require isn't enough to trigger it. Without refreshonly, it will run every time, but the desired behaviour is that "prereq" is run iff the onlyif command succeeds. Obviously the behaviour of "refreshonly => true" can't change, and I can't think of a good name for a tri-state alternative -- "refreshonly => 'requires-too'" ? "allevents" may be more workable. My prefered solution would be a new parameter "requireonly". Perhaps slightly misleading name, since "before" should trigger execution, too, but I think most people will understand that require/before are inherently intertwined. This could later be generalised into a metaparameter to work for more types, e.g. you could have a parent File which is only checked/updated/created when some other File requires it. -- You have received this notification because you have either subscribed to it, or are involved in it.
