The super-user root account, reserved for the machine's administrator, is automatically created during installation; this is why a password is requested. The installer also asks for a confirmation of the password to prevent any input error, which would later be difficult to amend. Note that you can leave both fields empty if you want the root account to be disabled. In that case, the login for the root user will be deactivated and the first regular user — that will be created by the installer in the next step — will have administrative rights through <command>sudo</command> (see <xref linkend="sect.sharing-admin-rights" />).
حساب الجذر مخصص لإدارة الحاسوب، ويُنشأ آلياً أثناء التثبيت؛ لهذا السبب يُطلب تحديد كلمة سر. كما يطلب المثبت أيضاً تأكيد كلمة السر لتجنب أي أخطاء في الإدخال قد يصعُب تداركها لاحقاً.
