You got me curious so I did a little digging. My guess is it was never released, because Hoyt Axton did the theme song (My My My My Mitchell) but it doesn’t show up on his discography as an album or single. I suppose it’s possible they released a soundtrack without it, but that seems like it would have been even more of a flop.
Code written in Rust has been shown to have significantly fewer security vulnerabilities than code written in C. Distributions like Ubuntu ship a lot of security updates, so by switching to Rust-based utils, they can reduce their workload in the long run.
