class Packages(Operation_packages):
    """
    A class to manage package operations on a remote system using `dnf`.

    This class provides functionality to install or remove packages on Fedora/RHEL systems
    using the dnf package manager. It allows configuration of execution privileges and
    safety guards for package operations.

    Attributes:
        packages (List[str]): List of package names to install or remove.
        present (bool): If `True`, packages will be installed; if `False`, packages will be removed.
        guard (bool): If `False` the commands will not be executed.
        sudo (bool): If `True`, the commands will be executed with [sudo](file:///home/kim/reemote/reemote/command.py#L11-L11) privileges.
        su (bool): If `True`, the commands will be executed with [su](file:///home/kim/reemote/reemote/command.py#L12-L12) privileges.

    **Examples:**

    .. code:: python

        # Install packages on all hosts
        r = yield Packages(["nginx", "curl"], present=True)
        # Check if the operation was successful
        if r.cp.return_code == 0:
            print("Packages installed successfully")

        # Remove packages on all hosts
        r = yield Packages(["nginx", "curl"], present=False)
        # Check if the operation was successful
        if r.cp.return_code == 0:
            print("Packages removed successfully")

    Usage:
        This class is designed to be used in a generator-based workflow where commands are yielded for execution.

    Notes:
        - Commands are constructed based on the [present](file:///home/kim/reemote/reemote/operation_packages.py#L30-L30) flag to determine whether to install or remove packages.
        - Uses `dnf install` and `dnf remove` commands internally for package management.
        - Inherits from [Operation_packages](file:///home/kim/reemote/reemote/operation_packages.py#L4-L89) base class.
