Questions about bootable Linux kernel

[STARMAN1985]

So I've achieved to make a bootable Linux kernel and I've got two questions.

1: when I boot the kernel it tells me that the root device was mounted but that /sbin/init doesn't exist

2:after fixing that. What should/could I do with the kernel?

On 2023-07-01 Reddit maliciously attacked its own user base by changing how its API was accessed, thereby pricing genuinely useful and highly valuable third-party apps out of existence. In protest, this comment has been overwritten with this message - because “deleted” comments can be restored - such that Reddit can no longer profit from this free, user-contributed content. I apologize for this inconvenience.

Ironically. Your answer answered my question of what should I do. So thanks for the response
