What file contains the boot parameters for the Linux kernel during system startup?

The correct choice is based on the specific function and role of the file in the Linux boot process. The /boot/grub/grub.cfg file is essential as it contains the configuration settings for the GRUB bootloader, which in turn specifies the boot parameters for the Linux kernel. When the system starts, GRUB reads this configuration file to determine which kernel to boot and what parameters to pass to it.

The entries within grub.cfg detail the different kernels available, alongside any associated boot options, such as specifying root file systems or initiating specific recovery modes. Therefore, this file plays a crucial role in the boot process by defining how the kernel should be loaded and any parameters that might alter its startup behavior.

In contrast, while /etc/default/grub is also relevant to GRUB configurations, it primarily holds default settings that can be used to generate the grub.cfg, rather than the boot parameters themselves. The /boot/loader/entries/ directory is associated with a different boot manager, specifically for systems using systemd-boot or similar, and does not directly contain the kernel parameters in the same way as grub.cfg. Lastly, the /boot/vmlinuz file is the actual Linux kernel image and
