How does that mean the script is buggy? It would depend on what /bin/sh is
linked to on a particular system.

That's available for RHEL too. The question is whether it's worth modifying
libraries that are core to resource-agents, essentially for compatibility
with vanilla ksh. The conservative answer is no, although there is a case
to be made in favor of the change. The local keyword has been there for
years. A lot of shells besides bash support the local keyword, and even if
ksh is the default shell on a user's system, they can likely use a
different one if needed, as Gabriele has done.
