Setting list for settings.boot


Full Reference

settings.boot.init-parameters

Init parameters expressed as key/value pairs. If boot data exists at /proc/bootconfig, Bottlerocket generates the settings from this data on first boot. During the boot process, the init parameters pass via the kernel command line.

[settings.boot.init-parameters]
"log_level" = ["debug"]
"splash" = []
apiclient apply <<EOF
[settings.boot.init-parameters]
"log_level" = ["debug"]
"splash" = []
EOF
