    installer(8): Use pgrep(1) to check frontend/backend processes
    
    Use 'pgrep -x' to correctly match the frontend/backend processes.  This
    is simpler than the original ps+grep method and fixes the partial match
    problem.  For example, the old grep would incorrectly match the tail(1)
    process that was checking the `dfuibe_installer_debug.log` or
    `dfuife_curses_debug.log` debug logs.
