NAME

       sysctl.conf - sysctl preload/configuration file

DESCRIPTION

       sysctl.conf is a simple file containing sysctl values to be read in and set by sysctl.  The syntax is simply as follows:

	      # comment
	      ; comment

	      token = value

       Note  that  blank  lines  are ignored, and whitespace before and after a token or value is ignored, although a value can contain whitespace
       within.	Lines which begin with a # or ; are considered comments and ignored.

EXAMPLE

	      # sysctl.conf sample
	      #
		kernel.domainname = example.com
	      ; this one has a space which will be written to the sysctl!
		kernel.modprobe = /sbin/mod probe

       /run/sysctl.d/*.conf

NAME

       sysctl.d - Configure kernel parameters at boot

SYNOPSIS

       /etc/sysctl.d/*.conf

       /run/sysctl.d/*.conf

       /usr/lib/sysctl.d/*.conf

DESCRIPTION

       systemd uses configuration files from the above directories to configure sysctl(8) kernel parameters to load during boot.

CONFIGURATION FORMAT

       The configuration files should simply contain a list of variable assignments, separated by newlines. Empty lines and lines whose first
       non-whitespace character is # or ; are ignored.

       Note that both / and . are accepted as separators in sysctl variable names.

       Each configuration file is named in the style of <program>.conf. Files in /etc/ overwrite files with the same name in /usr/lib/. Files in
       /run overwrite files with the same name in /etc/ and /usr/lib/. Packages should install their configuration files in /usr/lib/, files in
       /etc/ are reserved for the local administration, which possibly decides to overwrite the configurations installed from packages. All files
       are sorted by filename in alphabetical order, regardless in which of the directories they reside, to ensure that a specific configuration
       file takes precedence over another file with an alphabetically later name.

EXAMPLE

       Example 1. /etc/sysctl.d/domain-name.conf example:

	   # Set kernel YP domain name
	   kernel.domainname=example.com
