On my Lion installation changes in the OSX Control Panel some settings are no longer saved eg. General oder Language. After reentering the Control panel again, the old settings are still in place. Some settings (e.g. Keyboard oder Sharing) are stored correctly.
The problem appeared after installing a SSD as a new startup drive. The user profile in question is still residing on the HDD (/Volumes/Data). In the User Extends settings the User folder is set to /Volumes/Data/Users/username. On the SSD at /Volumes/SSD/Users the is a hard link pointing to /Volumes/Data/Users/username.
Where are the settings stored? I suspect them to be found in ~/Library/Preferences? Is this correct?
