Last POC for me,
The worse ....
Works out the box, just did a configure make install scheme for skalibs, execline,s6, s6-rc,s6-linux-utils,s6-portable-utils, oblibs, 66, 66-tools, boot-66serv and added the -m option for 66-boot on the init file, that's all.
Hum , i'm a liar , the package console-data need to be installed.

Note: obviously, i create a tree boot, enabled the boot service on it, created a tree root and enabled the tty inside
