kernelstub

Automatically manage Linux kernel loading on (U)EFI. More information: https://github.com/isantop/kernelstub#usage.

• Configure the current kernel with default options:

sudo kernelstub

• Add custom kernel options:

sudo kernelstub {{[-o|--options]}} "{{quiet splash mitigations=off}}"

• Run in verbose mode with systemd-boot configuration:

sudo kernelstub {{[-v|--verbose]}} {{[-l|--loader]}}

• Copy kernel only to ESP without NVRAM changes:

sudo kernelstub {{[-m|--manage-only]}}

• Run a simulation without making any changes (dry-run):

sudo kernelstub {{[-c|--dry-run]}}

• Specify paths manually:

sudo kernelstub {{[-k|--kernel-path]}} /{{path/to/vmlinuz}} {{[-i|--initrd-path]}} /{{path/to/initrd.img}} {{[-e|--esp-path]}} /{{path/to/efi_partition}}

• Show current configuration:

sudo kernelstub {{[-p|--print-config]}}
