"Just rewrite it in Rust" is a bit meme-y, but what I wanted to highlight is how you can look at ZFS itself for inspiration. ZFS has checksums to detect bit rot; maybe you want a language with better support for contracts / static analysis. ZFS has zvols to expose virtual block devices for use with other filesystems; maybe you want a language with safe C interop; etc. Any improvement in safety over plain old C would be desirable, and even unsafe Rust is safer.
