perl -p -i -e "s/^#MaxSessions .*$/MaxSessions 40/" /etc/ssh/sshd_config
perl -p -i -e "s/^#MaxStartups .*$/MaxStartups 40/" /etc/ssh/sshd_config
==>The "perl -p -i -e" commands here are the only ones like them in the doc, and it kinda sticks out. For consistency (the script changed long ago), these should be changed to use sed:
===
sed -i -e "s/^#MaxSessions .*$/MaxSessions 40/" /etc/ssh/sshd_config
sed -i -e "s/^#MaxStartups .*$/MaxStartups 40/" /etc/ssh/sshd_config

perl -p -i -e "s/^bind_ip = .*$/bind_ip = 0.0.0.0/" /etc/mongodb.conf
==> should be
sed -i -e "s/^bind_ip = .*$/bind_ip = 0.0.0.0/" /etc/mongodb.conf
