I’m currently moving my servers running CentOS 7 and Oracle Linux 7 to Rocky Linux 8. Up until now, I’ve been handling automatic updates using
yum-cron with email notifications. This has been working perfectly for years.
Now I’m getting a grip on
dnf-automatic, which works similarly to
yum-cron. After installing the
dnf-automatic package, I have an
/etc/dnf/automatic.conf configuration file with annotations, and it’s more or less self-explanatory. On a side note, I noticed that contrary to CentOS, Rocky Linux does provide security meta-information about packages, so I get to choose between
default updates or only those flagged as
security updates, which is nice.
In the provided
automatic.conf configuration file sample, there’s a redundancy that’s a bit puzzling. First, there’s a section
[email] with the following default directives:
[email] # The address to send email messages from. email_from = firstname.lastname@example.org # List of addresses to send messages to. email_to = root # Name of the host to connect to to send email messages. email_host = localhost
But then below this, there’s another section named
[command_email] with some sort of overlapping redundancy:
[command_email] ... # The address to send email messages from. email_from = email@example.com # List of addresses to send messages to. email_to = root
I admit I’m a bit puzzled. Do I have to keep both sections?
