NAME
kmpath — retrieve kernel name and associated kernel component set information
SYNOPSIS
/usr/sbin/kmpath [-k]
/usr/sbin/kmpath -c [kernel_name]
/usr/sbin/kmpath -i [kernel_name]
DESCRIPTION
kmpath retrieves the main kernel file name and path information of the currently running kernel.
kmpath also retrieves the Kernel ID String (KIS) and the associated
/stand/dlkm.KIS
directory of the current or specified kernel.
Each kernel is composed of several distributed component files, the kernel component set, which use a defined naming convention, and are all required for a kernel to boot and run properly. During the process of configuring a new kernel, a unique Kernel ID String (KIS) is embedded into the kernel image. The main kernel file (by default
/stand/vmunix)
is associated to its component files via the KIS.
The
/stand/dlkm.KIS
directory
contains several of the kernel component set
files used by the DLKM infrastructure, including dynamically loadable kernel module images.
If no options are specified,
kmpath
returns the full path of the main kernel file of the currently running kernel, which constitutes the boot kernel path of the currently booted kernel (for example,
/stand/vmunix).
Options
The kmpath options have the following meanings:
- -k
Return the base name of the main kernel file of the currently running kernel (for example,
vmunix).
- -c [kernel_name]
Return the
/stand/dlkm.KIS
directory name. If
kernel_name
is not specified, KIS corresponds to the currently running kernel's
Kernel ID String. If
kernel_name
is specified, KIS corresponds to the specified kernel's KIS.
- -i [kernel_name]
If a
kernel_name
is not specified, return the KIS of the currently running kernel.
If a
kernel_name
is specified, return the KIS associated with the specified kernel.
FILES
- /stand/kernel_name
Main kernel file.
- /stand/dlkm.KIS
Directory containing DLKM-related elements of the kernel component set.
(KIS is the Kernel ID string in the corresponding kernel image).
- /stand/krs/KIS.p0
Kernel-specific kernel registry file. Element of the kernel component set that contains
kernel-specific configuration data persistent across system reboot.
(KIS is the Kernel ID string in the corresponding kernel image).
- /stand/boot.KIS
Directory that contains links to the files in the kernel component set
that are required by the boot loader during the process of booting a kernel with Kernel ID String KIS.
