    1. before_destroy callbacks should be placed before dependent: :destroy associations (or use the prepend: true option), to ensure they execute before the records are deleted by dependent: :destroy.
    1. ssh doesn't let you specify a command precisely, as you have done, as a series of arguments to be passed to execvp on the remote host. Instead it concatenates all the arguments into a string and runs them through a remote shell.
