Problems with Persistant Home in 3.8.1

Not really a problem but could simplify my day. :?
I've set up a tohd install of 3.8.1 to a usb2 hdd (sda1) and have PH on sda2
It works as it should but when booting up I get a screen about how I wanna configure PH. Overwrite, System settings ... (can't remember all the options) and if I not answer in 20 seconds it cancels the sda2-based PH and uses a standard ramdisk one.
Is there a way to disable this question? I'd like to use my PH without having to answer this on every boot.
