Tesla cars use 'runit' for Linux init system (as opposed to systemd, etc.) (old.reddit.com)

I'm always interested in learning about things like this. For example, it was really neat to learn that the Intel SME ran the Minix microkernel. Or it was neat to learn that the Apple secure enclave was running the L4 microkernel.

It is a custom version of runit, moreover. Vanilla svlogd does not have -L and -M options.
