I'm not sure how it is currently implemented in SI, but I see the following problems with this suggestion: 1. If I understand correctly the ordering with a number prefix does only work within a class. So for example if I have a script 10all.configuresomestuff and some other *all-scripts depend on the changes made by this script, I can't override this script for some other group. The group scripts will only run, after all dependent *all-scripts are already run. 2. You can't really 'override' a script, so that e.g. the group-script will run INSTEAD of the all-script, you can only revert the changes made by these higher level scripts (if they are reversible at all). Instead I suggest the following scheme: 1. Ordering is global between all classes, so a 10all.script will run after a 09GROUPNAME.script, but before a 11GROUPNAME.script. If you don't want that you can achieve the same ordering as above by renumbering your scripts (this could even be done automatically when upgrading from a previous version). 2. You can override a script by choosing the same name and number for a script, but with a different scope. So for example if you have a script 10all.networking and a script 10MYGROUP.networking, then 10MYGROUP.networking will run on every host in the 'MYGROUP'-group INSTEAD of the 10all.networking script. On all other hosts the 10all.networking script will run obviously. If you don't want this behavior you can simply choose another name or ordering (or simply call the overridden script from your script). This would also be more similar to the way the master-script is choosen. In fact except for the numeric part at the beginning the logic is exactly the same! Just my 2ct... And yes, I realize I'm probably totally wrong here, it will horribly break backward compatibility and I'm a complete newbie ;-) Thanks for listening, Thomas Krause ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
