... pain LESS.  PainLESS.  Complete absence of pain.

> I updated my five Fedora servers this weekend via dnf, and it was 
> pretty uneventful.  On four out of five servers, I will even go so far 
> as to say it was painful.
> The fifth server, though ... there was a very poorly-timed brief power 
> outage in the middle of the process.  I was afraid I'd bricked the 
> server, but fortunately, the server booted up okay, and was willing to 
> do the update like nothing happened.  It was crazy slow, though, like 
> 12 hours or so.  So I get the feeling the power outage did confuse the 
> update process, but the update process worked through it rather than 
> giving up in frustration. Well done, Fedora 23!
>> I've been upgrading my Fedora boxes for some time now.  The last full
>> installs I did was for Fedora 21, when I purchased a SSDs for my 
>> laptop and
>> desktop.  Upgrades have been pretty seamless using 'fedup'.
>> With Fedora 23, they've changed it slightly by using 'dnf'.  So, read 
>> up on
>> the changes if you plan to upgrade.
>> Here are a few notes from upgrades I've done in the past couple days.
>> My laptop downloaded all the packages, but couldn't set up for the 
>> reboot
>> because of a conflict in one of the installed rpmfusion base packages -
>> there was still a Fedora 21 version in there.  Not sure why the F22
>> rpmfusion packages didn't replace it, but removing it resolved my issue.
>> (I'm referring to the actual rpmfusion repo config rpm).
>> My desktop was a bit of a different matter.  I have a Nvidia 630 card
>> installed and have been using the nvidia binary drivers for some time -
>> mostly for video acceleration when editing and playing back video.  As
>> Fedora 23 contains a release candidate version of the 1.18 X server, the
>> Nvidia driver ABI has not been updated to work with it.  Nvidia will 
>> only
>> update their driver once the full release of 1.18 is available. Of 
>> course,
>> I found this out after I upgraded.  So, searching some forums I found 
>> that
>> you can downgrade the X server to the Fedora 22 version.  Which is 
>> what I
>> did - I'm running the Fedora 22 version of X and the most recent 
>> Fedora 22
>> kernel with the RPMfusion nvidia driver.
>> Downgrade command:
>> dnf --releasever=22 downgrade xorg-x11-server-Xorg
>> Until such time that the full version of 1.18 is out and nvidia updates
>> their driver, I've excluded any X updates in the /etc/dnf/dnf.conf file:
>> .... clip here ....
>> exclude=xorg-x11-*
>> .... clip here ....
>> If you don't feel up to making all these changes, perhaps waiting a 
>> month
>> (hopefully) to upgrade to Fedora 23 would be the best course of 
>> action.  I
>> would have waited to upgrade my desktop had I paid more attention to 
>> some
>> of the forum posts from a few weeks ago.
>> If you're using an intel graphics adapter or the nouveau driver, you 
>> should
>> be fine.  Those with optimus hardware or the latest nvidia cards should
>> probably wait.
