| | 35 | .Sh DESCRIPTION |
| | 36 | The |
| | 37 | .Pa /etc/sysctl.conf |
| | 38 | file is read in when the system goes into multi-user mode to set default |
| | 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.\& |
| | 45 | .Bd -literal -offset indent |
| | 46 | sysctl_mib=value |

| | 70 | .Fx 4.0 . |
| | 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. |
