Motivation for this change
Volume salvaging was partly broken. Parallel building is also broken.
Some fixes and improvements:
Please update the commit author with
User and server binaries cannot be shipped separately. The bos tool uses a hard-coded path to the volume salvage command (which resides with the server binaries). Splitting them into separate outputs invalidates the reference in the bos tool (due to remove-references-to). This rendered the volume salvager inoperable (which is obviously a bad thing).
