|
.Nm kget

|
.Nd print kernel change information.
|
|
.Sh SYNOPSIS
|
|
.Nm kget
|
|
.Ar filename
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility allows one to view or save any device configuration information
|
|
which was changed in userconfig (-c) session. Most typically, it is written
|
|
to a /boot/kernel.conf file which is then loaded from /boot/loader.rc
|
|
(using "load -t userconfig_script /boot/kernel.conf"), saving the user
|
|
from having to re-enter it each time the system is booted.
|
|
.Pp
|
|
.Nm
|
|
uses the
|
|
.Xt sysctl 3
|
|
interface to retrieve data from the kernel and requires that at least
|
|
the
|
|
.Ar machdep.uc_devlist
|
|
symbol be present. If it's not, you may need to update your kernel
|
|
before using this utility.
|
|
.Pp
|
|
Usage:
|
|
.Nm
|
|
.Ar filename

|
|
standard output should be used.
