+git-annex has detected problems with the filesystem, since symlinks
+work I think it detected that the filesystem allows writing to a
+file even when the file's write bit is not set.
+
+In that situation, a git-annex repository using symlinks will apprear to
+work, but if you have an annexed file "foo" in there, and run "echo hi >
+foo", it will follow the symlink, and overwrite the annexed file, ignoring
+the lack of write bit. This can result in data loss in an unexpected way,
+which is why git-annex avoids using the symlinks in this situation.
+
+I've added an additional message to make more clear what is happening.
