Table 6 Boot Flags

Flag Meaning
-d Debug mode. Enters the kernel debugger as soon as possible in the kernel initialization.
-m This flag is used on flash-based (diskless) systems to set the miniroot variable to 1.
-r File system read-only after rebooting. You might want to use this while doing maintenance tasks.
-s Single-user mode, which removes your system from the network. To perform certain system
tasks, such as resetting the password, you must boot in single-user mode. If the console is
marked as insecure, you must enter the root password to access the manager.
Exit single-user mode by pressing Control + D, or by pressing Enter, after which the system
restarts.
-v Verbose mode. Verbose during device probing and thereafter.
-x Instructs the system not to identify the flash disk as wd0. Rarely used.
