Since enabling FileVault (I think only after I did that for my second hard drive), the desktop background keeps resetting to the default at every startup. It suffices to select another folder in System Preferences -> Desktop to make it switch back to the one chosen by me, I don't have to actually set it explicitly again.
Does anyone experience the same issue?

Ok, it just occurred to me that the answer is obvious: OS X cannot access my Wallpapers folder which is on the second drive, before I have entered the password for using the drive, which obviously happens after the desktop is rendered. Solution: Move the wallpaper to the boot drive.
