NAME

       linux-boot-prober -- Determine boot characteristics of a specified device.

SYNOPSIS

       linux-boot-prober <partition>

DESCRIPTION

       The  linux-boot-prober  utility will try to work out how to boot the linux root partition specified by <partition>.  If successful, it will
       outoput one or more lines of the form:

       <root partition>:<boot partition>:<label>:<kernel path>:<initrd path>:<kernel parameters>

       For example, for a system with a kernel at /boot/vmlinuz and an initramfs at  /boot/initrd.gz,  and  with  /  on  /dev/sda2  and  /boot	on
       /dev/sda1, the command "linux-boot-prober /dev/sda1" will display:

       /dev/sda2:/dev/sda1:Linux:/vmlinuz:/initrd.gz:root=/dev/sda1

       Some partitions will not be displayed by linux-boot-prober.  If a partition is mounted on /, /target, or /target/boot, it will be skipped.

NAME

     boot.config -- Configuration file for the boot blocks

DESCRIPTION

     The boot.config file contains options for the FreeBSD boot block code.

     When the FreeBSD boot loader runs, it searches the ``a'' slice of the boot partition for a boot.config file (as a result, slices which are
     missing an ``a'' partition require user intervention during the boot process).  If the boot.config file is found, its contents are used as
     the default configuration options for the boot block code and are echoed to the system console.

     A valid format of this file is to put BIOS drive number, a controller type, a unit number, a partition, a kernel file name, and any other
     valid boot(8) option on a single line, as it is done at the ``boot:'' prompt.

     The options related to the boot image selection described below and all the other options available for boot.config are documented in detail
     in the boot(8) manual page.

FILES

     /boot.config  parameters for the boot blocks (optional)

EXAMPLES

     The command:

	   # echo "-P" > /boot.config

     will activate the serial console of FreeBSD.

     The command:

	   # echo "1:ad(1,a)/boot/loader" > /boot.config

     will instruct the second stage of boot(8) on the first disk to boot with the third boot(8) stage from the second disk.

     The command:

	   # echo "1:ad(1,a)/boot/loader -P" > /boot.config

     will do both of the above.
