It's used by the true command as the source of truth for what the return code is.

Edit: I found a copy of the file and verified it:

$ xxd -c 8 true.dat | head -n 4
00000000: 0000 0000 0000 0000  ........
00000008: 0000 0000 0000 0000  ........
00000010: 0000 0000 0000 0000  ........
00000018: 0000 0000 0000 0000  ........
$ 

As you can see, it's all zeroes, which is what the return code for true should always be.
