The boot configuration expands the current kernel command line to support additional key-value data when booting the kernel in an efficient way. This allows administrators to pass a structured-Key config file. There are two options to boot the kernel with bootconfig: a) attaching the bootconfig to the initrd image or b) embedding it in the kernel itself. I'd like to see option a) implemented in genkernel, ideal pass an genkernel command line like: --bootconfig=/path/to/my/bootconfig.txt see the link for more info: https://docs.kernel.org/admin-guide/bootconfig.html Reproducible: Always
