I don't know a sysadmin on this planet that dreams of using Ruby as systems scripting language. That sounds like hell.

Again, its the trade off between a relatively simple port and adopting a new language with different standards, technical difficulties and culture.

I would love that. Ruby has become my go-to language for quick scripts, even in places where bash does the job. Bash is for things where I can keep everything in my head and there aren't too many lines. Ruby for everything else.
