Yum replaced by DNF - Followup

Well, recently came into the problem that I had some configuration that requires porting, I think. I wanted to get into the DNF scene, whilst Centos 7 still uses yum by default.

From Yum to DNF

I installed dnf, simply using.

yum install dnf

The packages yum, yum-plugin-fastestmirror, yum-utils are now no longer needed. Your original configuration file can then be found in yum.conf.rpmsave.

I installed "dnf-yum", to be able to use yum as a automatic redirect to dnf.

Yum.conf

The /etc/yum.conf shall have been replaced with /etc/dnf/dnf.conf.

Yum cron jobs

In DNF, this is replaced by the package "dnf-automatic"³. The configuration of which is in /etc/dnf/automatic.conf.

Removed package yum-cron as it is no longer needed.

To get started:

systemctl enable dnf-automatic.timer && systemctl start dnf-automatic.timer

To list the timers set:

systemctl list-timers *dnf-* -all

Excluding packages

I have added the java* packages to the exclude directive in yum.conf¹.

Of course, I do wish to manually install the java updates along with all the other updates². To do this I can use the command line:

yum --disableexcludes=all update

These switches in the commandline and changes in the config file of yum are ported identically over to dnf. So that's not a problem.

Yum Repos

Apparently, DNF still uses all the repositories defined under /etc/yum.repos.d. So that's a relief.
