A RHEL6 installation complained:
“DeprecationWarning: Call to deprecated function: hasNow”
in /usr/libexec/rhsmd .
According to RedHat, this is not a problem, as rhsmd is working fine.
Workaround in order to stop seeing the mails:
# diff /tmp/rhsmd /etc/cron.daily/rhsmd 5c5 < /usr/libexec/rhsmd -s --- > /usr/libexec/rhsmd -s 2>&1 | grep -v DeprecationWarning
