The kernel is started by the boot loader. The boot loader delivers environment variables to the kernel. Together they form the ''kernel environment.'' The kernel and its environment form also a MIB tree, like the [[sysctl]] tree.  With the [https://www.freebsd.org/cgi/man.cgi?query=kenv&apropos=0&sektion=0&manpath=FreeBSD+12.1-RELEASE+and+Ports&arch=default&format=html kenv(8)] utility you can view the kernel environment.

The simplest and best supported way to alter a kernel is to use the '''[[sysctl]]''' interface. The [https://www.freebsd.org/cgi/man.cgi?query=sysctl&apropos=0&sektion=8&manpath=FreeBSD+12.1-RELEASE+and+Ports&arch=default&format=html sysctl(8)] allows you to retrieve the values used by the kernel and in some cases to set them.
