SYSCTL.CONF(5) File Formats Manual SYSCTL.CONF(5)
NAME
sysctl.conf – kernel state defaults
DESCRIPTION
The /etc/sysctl.conf file is read in when the system goes into multi-user
mode to set default settings for the kernel. The /etc/sysctl.conf is in
the format of the sysctl(8) command, i.e.
sysctl_mib=value
Comments are denoted by a “#” at the beginning of a line.
FILES
/etc/sysctl.conf Initial settings for sysctl(8).
EXAMPLES
To disable coredumps, you may use a configuration like:
# Disable coredumps.
kern.coredump=0
SEE ALSO
sysctl(8)
HISTORY
The sysctl.conf file appeared in FreeBSD 4.0.
BUGS
If loadable kernel modules are used to introduce additional kernel
functionality and sysctls to manage that functionality, sysctl.conf may
be processed too early in the boot process to set those sysctls.
