/etc/rc.d/sysctl
rc(8) script which processes sysctl.conf early on in the process of transitioning to multi-user mode.
sysctl.conf5
Kernel state defaults
Overview
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 file 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. Comments can also exist at the end of a line, as seen in the EXAMPLES section, below.
For kernel modules loaded via rc.subr(8) system, additional module-specific settings can be applied by adding a file in the same format named /etc/sysctl.kld.d/<modulename>.conf.
