第 12 章 Managing kernel arguments in bootc systems

You can use bootc to configure kernel arguments. By default, bootc uses the boot loader configuration files that are stored in /boot/loader/entries. This directory defines arguments provided to the Linux kernel. While kernel arguments are machine-specific, you can manage them through container updates. The boot loader menu entries are shared between multiple operating systems and boot loaders are installed on one device.

# /usr/lib/bootc/kargs.d/10-example.toml
kargs = ["mitigations=auto,nosmt"]

# /usr/lib/bootc/kargs.d/00-console.toml
kargs = ["console=ttyS0,115200n8"]
