WITH_DEXPREOPT and ART configuration

[Kyle]

If I use WITH_DEXPREOPT := true when building my Android system image, it sounds like this includes the precompiled OAT files in the system image so that my first boot is faster.  However, it looks like ART still attempts to relocate system apps from /system to /data during boot.

Is this expected?  Or am I misunderstanding the impact WITH_DEXPREOPT is supposed to have?

(For reference, I'm building Lollipop 5.1.1)

You also need:

WITH_DEXPREOPT_PIC := true
