After a week of tablet-only availability, Google has released Android 5.0.1 factory images for the Nexus 6 and Nexus 4 (wherefore art thou, Nexus 5?).
The builds are identical, LRX22C, and can be used to flash devices to factory fresh settings, or, by flashing the .img files separately, overwriting existing Lollipop builds. It doesn’t appear the over-the-air updates are being sent to either device yet, so this is currently the only way to update a Nexus 4 or Nexus 6 to the latest bug-fixing Lollipop build.
Instructions on how to flash are available here.
