The `set-root-password` command sets up an alternate mount namespace with a writable `/etc` directory and then runs `passwd` in it. This allows `passwd` to create its lock files and backup files, without requiring that the real `/etc` to be mutable. After `passwd` finishes and has updated its private copy of `/etc/shadow`, the script rewrites the real one with its contents.
