DNF (Experimental Yum Replacement)

In order to test DNF (Dandified Yum) we can follow these steps:

# yum install -y dnf
# dnf install fedora-release-rawhide
# dnf upgrade --enablerepo=rawhide
# cat /etc/fedora-release 
Fedora release 22 (Rawhide)

Take into account that this also will upgrade our machine to Fedora Rawhide.

As a command reference it’s almost equal to yum syntaxis:

Eudyptula Challenge completed

No updates means that I was busy 🙂

So finally I got to finish Eudyptula challenge and I would like to recommend you once again to try it and finish it.

I’ve learned so many things about the kernel that without the “guidance” of little I wouldn’t be aware of.

And if you’re curious that’s a quote from little:

Very nice job, you are now done!

If you were curious, you are the 50th person to complete the series of tasks, with over 7100 people currently attempting it. It’s not a race, but you’ve done a great job.
