+### Please describe the problem.
+
+`annex init --help` talks about supporting `--backend` so I expected either modification of .gitattributes to add backend, or at least non-persistent setting in .git/config ... but seems nothing is actually done?
+
+
+### What version of git-annex are you using? On what operating system?
