userconfin-kernel device configuration manager

options USERCONF

userconf is the in-kernel device configuration manager. It is used to alter the kernel autoconfiguration framework at runtime. userconf is activated from the boot loader by passing the -c option to the kernel.

The general command syntax is:

command [option]

userconf has a more(1)-like functionality; if a number of lines in a command's output exceeds the number defined in the lines variable, then userconf displays “-- more --” and waits for a response, which may be one of:

<return>
one more line.
<space>
one more page.
abort the current command, and return to the command input mode.

userconf supports the following commands:

count
Specify the number of lines before more.
8 | 10 | 16
Base for displaying large numbers.
devno | dev
Change devices.
devno | dev
Disable devices.
devno | dev
Enable devices.
A synonym for quit.
devno | dev
Find devices.
Display online help.
List current configuration.
Leave userconf.
A synonym for help.

The userconf framework first appeared in OpenBSD 2.0, and was then integrated into NetBSD 1.6.

The userconf framework was written by Mats O Jansson <moj@stacken.kth.se>.
