+On the `distributedmigration` branch I have `git-annex migrate` recording
+migrations on the git-annex branch.
+
+Its method of grafting in 2 trees, one with the old keys and one with the
+new is quite efficient. In a migration of 1000 files from SHA256E to SHA1,
+the git objects only needs 52kb to record the migration trees. 
+Compared with 424 kb needed to update the location logs. 
+The total git repo grew from 508kb to 984k.
+
+Next up: Make `git-annex migrate --update` find new migrations started
+elsewhere and apply them to the local annex objects.
