MAAS can specify kernel boot options to machines on both a global basis (UI and CLI) and a per-machine basis (CLI-only). A full catalogue of available options can be found in the Linux kernel parameters list at kernel.org.
Two questions you may have:
- How can I set global kernel boot options for all machines?
- How can I set kernel boot options for a specific machine?
Global kernel boot options
You can set kernel boot options and apply them to all machines with the CLI command:
maas $PROFILE maas set-config name=kernel_opts value='$KERNEL_OPTIONS'
