SYSCTL.CONF(5) | NetBSD File Formats Manual | SYSCTL.CONF(5)

# NAME

sysctl.conf — sysctl configuration file

# SYNOPSIS

sysctl.conf |

# DESCRIPTION

The sysctl.conf file defines the sysctl(7) kernel state tunables that can be set at boot time using sysctl(8) (using the -f switch) via the /etc/rc.d/sysctl startup script.

The state to be set is described using a “Management Information Base” (“MIB”) style name. The MIB and value must be separated by ‘=' with no whitespace, for example:

name`=`value

Blank lines, lines with just name, and comments (beginning with ‘#') are ignored. Line continuations using backslash ‘\' are permitted. Only integral and string values can be set.
