Yes, it should be created by blkid automatically when udev runs it to probe detected disks. The fact that /etc/blkid.tab is a symlink is just to allow the file to be read/write even when / is mounted read/only.

Can you run blkid -p /dev/sda and post the output, and see if that creates the /dev/.blkid.tab?
