** XX this is quite bad, and doesn't share much in common with
-** the rest of unix.c. at minimum it should instead take pax as
-** a noun and build the C path from that. it would also be nice
-** if it could take a u3_udir or something corresponding to the
-** base directory.
+** the rest of unix.c. a refactor would probably share common
+** logic with _unix_sync_change, perhaps using openat, making
+** unx_u optional, and/or having a flag to not track the file
+** for future changes.
