You have been subscribed to a public bug by Stefan Rijnhart (Therp) (stefan-therp):

If I delete one of a module's standard configuration records, then
upgrading the module recreates that record. This happens even when the
noupdate attribute has been set. For example, when I delete a unit of
measure, it comes back.

I suspect this may have been a design change in v6.0 instead of a bug.
If that's true, will I cause myself problems by changing it back? Was
there a reason for the change, or did some users just prefer the new
behaviour?

Steps to reproduce:
1. Create a blank database with no demo data using version 6.1.1.
2. From the Settings menu, choose Modules: Modules.
3. Turn off the Apps filter and install the product module.
4. From the Settings menu, choose Users: Users.
5. Open the admin user and go to the Access Rights tab.
6. Set the Sales Management level to Manager, and turn on the Extended View.
7. Reload the main menu. From the Sales menu, choose Configuration: Products: Units of Measure: Units of Measure.
8. Delete the "g" record.
9. Go back to the Modules screen and upgrade the product module.
10. Go back to the Units of Measure screen and click the Find button.

Expected behaviour: the "g" record should stay deleted because product_data.xml used noupdate="1".
Actual behaviour: the "g" record is recreated.

Workaround: instead of deleting the record, mark it inactive.

Impact:
There's no way for a user to tell whether a record is a standard configuration record or was added by a user, so they can't tell whether they're allowed to really delete it or they have to deactivate it. If I decide to live with the new behaviour, then I think I'll just have to tell the users not to delete any records from screens in the configuration menus. I guess that's probably a good policy anyway, because they can't easily tell whether it's being referenced by any child records.
Where it's really biting us, though, is the migration process from version 5.0 to 6.0. Any records that we deleted, like currencies, are unexpectedly reappearing and causing errors.
