    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.
    
    NOTES
           As the /etc/sysctl.conf file is used to override default kernel parame‐
           ter values, only a small number of  parameters  is  predefined  in  the
           file.   Use  /sbin/sysctl -a  or  follow sysctl(8) to list all possible
           parameters. The description of individual parameters can  be  found  in
           the kernel documentation.
    
    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
