+### Please describe the problem.
+I tried git annex init on a worktree checkout of a branch, but got an error (see below).
+The worktree is for a repo that is itself a submodule of another repo.
+
+### What steps will reproduce the problem?
+I can try later to make an isolated reproducible example, but I think the above scenario describes it.
+
+### What version of git-annex are you using? On what operating system?

+### Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)
+Well I keep coming back to it as a solution :)  Right now I'm trying to set up proper test cases for a tool that processes sequencing data, and even moderate-size test files break github's size limits.  I'm also planning to demo git-annex to others in my group so they can start using it.
