Because my old kernel on sh4 CPU can not support systemd.
I decide to install sysvinit scripts and the init system files.
But, I don't know how to get those old files?
Can anyone tell me where to grab?
I know there are a couple projects on github where you can find a (somewhat) maintained initsccripts. Other than that though I think the Arch Rollback Machine might be able to provide you with these if you go back far enough.
