doc/bugs/git_annex_adjust_--unlock_seems_to_cause_migration_of_a_file_to_another_backend.mdwn

+### Please describe the problem.
+
+Interestingly, on my first attempt I had two files which migrated from MD5 to MD5E backend, but may be I have done some steps differently which provoked also  also utils/test/test_data.tar.gz to get to the same destine.  I am a bit confused why git diff reports change in the symlink if file is already a real file (I guess all the smudging magic)
+
+### Please provide any additional information below.
