| 39 | settings for the kernel. | |
| 40 | The | |
| 41 | .Pa /etc/sysctl.conf | |
| 42 | is in the format of the | |
| 43 | .Xr sysctl 8 | |
| 44 | command, i.e.\& | |

| 71 | .Sh BUGS | |
| 72 | If loadable kernel modules are used to introduce additional kernel | |
| 73 | functionality and sysctls to manage that functionality, | |
| 74 | .Nm | |
| 75 | may be processed too early in the boot process to set those sysctls. |
