# Upstream's listing of required modules is NOT correct!
# Some of the postgres plugins use DBD::Pg, while others call psql directly.
# Some of the mysql plugins use DBD::mysql, while others call mysqladmin directly.
# We replace the original ipmi plugins with the freeipmi_ plugin which at least works.
