Ensure authentication required for single user mode
OrtaDüzey 1Otomatikcos
Açıklama
Single user mode (rescue mode) is used for recovery when the system detects an issue during boot or by manual selection from the bootloader. Requiring authentication in single user mode (rescue mode) prevents an unauthorized user from rebooting the system into single user to gain root privileges without credentials.
