# Kernel command-line options
|
|
|
|
The kernel command-line is a string of text that the kernel parses as it is starting up. It is passed by the boot loader
|
|
to the kernel and specifies parameters that the kernel uses to configure the system. The command-line is a list of command-line
|
|
options separated by spaces. The options are parsed by the kernel and can be used to enable or disable certain features.
|
|
|
|
LinuxKit passes all command-line options to the kernel, which uses them in the usual way.
|
|
|
|
There are several options that can be used to control the behaviour of linuxkit itself, or specifically packages
|
|
within linuxkit. Unless standard Linux options exist, these all are prefaced with `linuxkit.`.
|
|
|
|
| Option | Description |
|
|
|---|---|
|
|
| `linuxkit.runc_debug=1` | Start runc for `onboot` and `onshutdown` containers to run with `--debug`. Also sends output to the console, in addition to the normal output to logfiles. If not present or set to 0, default to usual mode. |
|
|
| `linuxkit.unified_cgroup_hierarchy=0` | Start up cgroups v1. If not present or set to 1, default to cgroups v1. |
