I'm trying boot the system with a single bootloongarch64.efi and got stuck on mounting
rootfs. It turns out to be the malfunction of kernel which dropped my built-in command
line. It's quiet annoying to be lacking a feature compared to other architectures.
Also, a feature shown in config should be functioning, or be considered buggy and get
fixed.
