Jail is set up, and crontab is set up to run rcynic hourly, at
a randomly selected minute (to spread load on the rsync
servers). Please do NOT adjust this to run on the hour. In
particular please do NOT adjust this to run at midnight UTC.
You may need to customize $jaildir/etc/rcynic.conf. If you
did not install your own trust anchors, a default set of
SAMPLE trust anchors may have been installed for you, but you,
the relying party, are the only one who can decide whether you
trust those anchors. rcynic will not do anything useful
without good trust anchors.
