So.
How to do this?

this is packages fbsplash or/and fbcondecor

i saw several faqs but cant complete understand overall picture.

Need turn on in kernel these options

General setup  --->
    [*] Initial RAM filesystem and RAM disk (initramfs/initrd) support
Device Drivers  --->
    [*] Block devices  --->
        <*>   RAM block device support
Device Drivers  --->
    Graphics support  --->
        {*} Support for frame buffer devices  --->
            *** Frame buffer hardware drivers ***

In Devuan kernel they are active?

maybe this links can tell what i mean
