RustyBox is a c2rust port/rewrite of BusyBox to Rust; though it doesn't look like anyone has contributed fixes to the unsafe parts in awhile. So, no SysV /etc/init.d because no shell scripting, and no systemd because embedded environment resource constraints? There must be a process to init and respawn processes on events like boot (and reboot, if there's a writeable filesystem)

Yes, you are right, I am trying to create a smaller version of sysvinit compatible with busybox's init. There is still no shell scripting yet, but I do promise to make the shell fully compatible with other shells with shell scripting in a future version. What happened to RustyBox? c2rust is way easier than doing it manually, then why is it abandoned?

  Same question about rustybox. Maybe they're helping with cosmos-de or coreutils or something. OpenWRT has procd instead of systemd, but it does source a library of shell functions and run [somewhat haphazard] /etc/init.d scripts instead of parsing systemd unit configuration files to eliminate shell scripting errors when spawning processes as root. https://westurner.github.io/hnlog/ https://westurner.github.io/hnlog/ Ctrl-F procd, busd (This re: bootloaders, multiple images, and boot integrity verification: https://news.ycombinator.com/item?id=41022352 https://news.ycombinator.com/item?id=41022352 ) Systemd is great for many applications. Alternatives to systemd: https://without-systemd.org/wiki/index_php/Alternatives_to_systemd/ https://without-systemd.org/wiki/index_php/Alternatives_to_s... There are advantages to systemd unit files instead of scripts. Porting packages between distros is less work with unit files. Systemd respawns processes consistently and with standard retry/backoff functionality. Systemd+journals produces indexable logs with consistent datetimes.
