+If .git/annex/tmp is a symlink to another fs, then adding doesn't work:
+
+    add file1.jpg (checksum...) 
+    git-annex: /path/to/.git/annex/tmp/tmp30148: rename: unsupported operation (Invalid cross-device link)
+
+It looks like it would be good to have two types of tmp directories here, one for adding, another one for verifying (and that one could be redirected off SSD).
