We have a couple of modules that are used to set up our implementation test environments (set up companies, charts of accounts, default settings etc). Nice way to quickly get a test database up and running. But the problem is that with a OpenERP update (one openerp_7.0-latest-1_all.deb to the next) the modules are reinitialised and fails with it tries to set the companies again.

How do we stop the custom add-on modules re-installing?
