This also happens when _editing_ an existing file because "backup by
renaming" will move the old file aside and the new version of file is
really creating a new file.

So, if you want to give your /etc/passwd and /etc/shadow the -rwxrwxrwx
permissions just edit the files with tramp's /su or /sudo method while
having backup by renaming enabled.
