Hi everyone, I'm curious what would happen in btrfs if the following commands were issued: # cp file1 file2 # chown newuser:newgroup file2 Where file1 was owned by olduser:oldgroup. If I understand copy-on-write correctly the "cp" would merely create a new pointer (or whatever it is called :( ) containing the files' metadata but the file contents would not actually be duplicated. Then the "chown" would change the metadata so that file2's metadata indicates newuser:newgroup owned the file contents. At the same time the metadata of file1 would say that olduser:oldgroup owned the file contents. (If a user modified the file contents, the contents would be copied at that time.)
