Any valuable linux project to join?

No. I would not say the above projects are as ambitious in scope as "util-linux 
in Nim". Anyone doing that would be well advised to reach beyond a "simple 
clone in another prog.lang" which has little value to users. At the very least 
they should use `cligen` to get nice colorized tabular auto-help with 
spell-checking/abbreviating options parsing. :-)
