I agree that inter-version compatibility could be a problem with
Python. But to take this argument literally, the best way to avoid
compatibility issues is to use the widest-spread and most version
consistent language across supported distributions, ie. bash.

Since only RHEL, CentOS and SLES are supported, should we really care
about python versions in Ubuntu?
When installing Lustre in Ubuntu, users already have to do their own
packaging, so I'm not sure that having to install a specific version
of a scripting language would make much of a difference.

So what's wrong with bash again? If it's just "too flexible, easy to
abuse", I'm afraid there's little in Perl to prevent falling into the
same pitfalls. :)
