The order of things…

Me again... I'm just wondering how people find the best order to put things in your instaDMG work flow other than by trial and error which when you have a lot of software and a large final image size (like me) can be somewhat time consuming. I can get 2 complete run throughs a day of the full image at present unless I leave stuff out that I know works fine. So leaving stuff out is what I have been doing as well as using composer to build custom builds of software for example iLife 09. I can build a single, fully patched iLife 09 pkg using composer which means i don't have to use the base installer then add the updates in my work flow. This saves a bit of time each run through as well as reducing the number of moving parts to use a mechanical analogy. I'm just trying to work out what interacts with what in the process and if there is a great deal of importance to be placed on which installers go where in the scheme of things and if there are repercussions of the interactions between certain installers eg: is it better to put CS5 before iLife 09 or not or does it matter at all or, does Office 2011 effect CS5 or Final Cut Studio if placed after it on the work flow. Perhaps this is an over analytical way of looking at the process but I have 3 master images to make for the beginning of semester 1 next year usually done monolithically. The largest is around 90 gig and contains some heavy app packages and i'm just trying to best out of the process and avoid any pitfalls. Regards Tristan
