... and having Shellshock vulnerability in mind, also a little bit
worring (yes, even nowadays).

(that being said, I've already presented my subversive opinion that
shell introduces more headaches than reasonable, as using it may be
most natural and with almost no barriers to entry, but it's actually quite
hard to make scripts bullet-proof; say chances the script will be derailed
just with a space-contained [not talking about quotes] parameter are
quite high: http://clusterlabs.org/pipermail/users/2015-May/000403.html)
