Hi,

I've been playing with OpenERP for a while, I learned some basic of OpenERP, but I found one thing that keeps me puzzled for a while.
You can make security files, and it's perfectly clear and easy to use once you lear them.
But, also, you can "manually"change user tights from within OpenERP, via Settings tab. But, when you reinstall you application, all your new settings are gone. 

For example, you can go to settings, click on Groups under Users menu from the left and change some settings (change some write/read rights or so). You can do this for many users and it works. But, when you finally reinstall your module, all this settings are gone, they are just as they were when you first install module.

My questions are following: 

- where OpenERP stores this "manually" changed rights- in database, in some hidden file or something else?

- how to save this settings in way that you can easy reload them when you reinstall your module?

Thanks in advance!
