update_messages = no setting in the /etc/yum/yum-cron.conf file all our CentOS 7.x based Vritualmin systems keep sending the following message:
Webmin install complete. You can now login to https://ns1.domain.tld:10000/
as root with your root password.
And it is so annoying when dealing with lot's of *min systems. We would really do appreciate if *-min developers started to put themselves in shoes of hosting vendors, which have to monitor root mails, but do not really have to receive so many annoying messages from Webmin. Please make the system little bit less verbose as end-users will be logging into their control panel some day and see new Webmin is installed anyway, so is there a real need to send those annoying messages?! :(
