which files is to init system and load kodi after linux kernel run?

i don't know which files to init system and load kodi after linux kernel run.

etc/init.d ,autorun.sh don't exist. and ".config/system.d" ".config/sysctl.d" have nothing .

wiki say how to edit /flash/config.txt but i can't find it and i find a file named "extlinux.conf" in extlinux directory. extlinux.conf is config.txt?

i can't find config files for busybox.....

where is start after linux kernel run?

Kodi is started (and managed) by systemd. What exactly are you trying to achieve?

i am studing embedded linux and try to find how system work. i find LE is special no as what my book say.

i think maybe my book is too old.

thank you very much.
