Apple, Please provide an Uninstall feature in your updates!

Question

After updating to 10.4.4, I can no longer connect to our XServe 10.3.8 server.
I have had other problems with updates as well on other computers.
It would be nice if Apple could borrow a feature from Windows XP that lets users rollback to previous configurations. Or simply provide an uninstaller. Or some easy way of removing the update. Microsoft 1, Apple 0. Not that I like Microsoft, but Apple needs to do something about this.
This has been very annoying having to wait for an update to fix an update.
I have done all of the required permission fixes and this is a brand new G5 so there shouldn't be any corrupted files.

The problem was not with the XServe or Keychain access. It was the update used in the software update service. Since I was going from 10.4.3. to 10.4.4, I didn't think I would need the combo update. Guess I was wrong to download the smaller file. I downloaded and installed the full Combo update and now it is seeing the XServe shared points.
Now back to the uninstall feature: My System X folder is 1GB. Surely that whole folder would not need to be cloned to uninstall a 55MB file. What about creating a temp file the holds only the files changed?
The problem with backups (especially if it is a server) is that new files are constantly created and would be lost if a restore needed to be done. That would be fine for a home user with only one Mac, but how many home users even have a backup system? It would take a long time to backup an 80GB drive to .Mac.
If an option was made available as a checkbox that asks the user..."Do you want to save the current state or configuration?" and then tell how much space it would take up. This file could then be deleted later in the Software update System Preference. Software Update should also have an option to "just download" or "download and install". Right now it immediately installs after downloading. What about an option to automatically download new updates. Install them when you choose. This would save time waiting for the downloads before installing. Again, Microsoft already has this feature.
Another feature I would like to see in the update process is...If repairing permissions needs to be done before installing, why doesn't the installer automatically do this during the install? The general public doesn't know to do this anyway.
I could go on and on about stuff I would like to see in OS X but I think I covered it for this topic.
