+# Files - what are they even good for?
+
+- How do we identify a tree of files in a useful way across different RB tools?
+    - that said, what should be the goal for file set identity?
+    - source trees?
+    - build tools?
+    - disk images?
+    - comparison-accelerator?
+    - content-addressed storage?
+
+- There should be a distinction between a file set (as an identity) and a file set (as a transport)
+- Existing work:
+    - go dirhash
+    - git tree hash
+    - nar hash
+    - bazel REAPI
+- some consensus on what these standards support, but not 100% consistency (x bit, xattrs, empty dirs, etc.)
+- some movement on order-independent hashing - potential for performance improvements in new standards
