+Suppose something goes wrong, and fsck puts all the files in lost+found.
+It's actually very easy to recover from this disaster.
+
+First, check out the git repository again. Then, in the new checkout:
+
+	mkdir recovered-content
+	sudo mv ../lost+found/* recovered-content
+	git annex add recovered-content
+	git rm recovered-content
+	git commit -m "recovered some content"
+	git annex fsck
+
+The way that works is that when git-annex adds the same content that was in
+the repository before, all the old links to that content start working
+again. This works particularly well if the SHA1 backend is used, but even
+with the default backend it will work pretty well, as long as fsck
+preserved the modification time of the files.
