I've been saying for the longest time that if you want to run RHEL/CentOS on the desktop and don't want to quickly hit a wall in terms of packages, you need to either run the Stella spin on CentOS, or use the developer of that project's repo to give your existing CentOS/RHEL system what it's otherwise lacking.
The way I look at it, without the Nux repo, you are going to miss a LOT of packages you're accustomed to seeing in Fedora, Ubuntu and Debian that you just don't see in Fedora, EPEL, El Repo and RPM Fusion.
Yep, three extra repos won't give you the desktop packages you need.
But the Nux repo will. And luckily at this point it's got hundreds of packages you might want or need for RHEL/CentOS 7.
I mentioned this in my CentOS 7 post but felt that it deserved to lead its own entry:
For those who want to run CentOS 7 on the desktop with minimal pain, take heart: Nux is prepping a CentOS 7 version of Stella
I was a big, big fan of Stella 6 -- I really think it's the only way to run CentOS on the desktop without pulling your remaining hair out. Nux has packages of just about everything you're missing in stock RHEL/CentOS. And for those who haven't really looked into it, RHEL/CentOS is missing a lot.
Stella isn't so much a derivative distro as it is a spin on CentOS that includes all the extra repositories you need to replicate the desktop experience of, say, Fedora, but in the supported-just-about-forever world of RHEL/CentOS.
Stella takes CentOS (which takes Red Hat Enterprise Linux) and adds many (many!!) of the desktop packages you're missing; along with
RPMForge/RepoForgethe EPEL repository, you're pretty much all the way there
It's nice to say that the very-very-very-long-term-support releases in the Linux world that won't cost you arms and legs -- the RHEL-source-fed CentOS and Scientific Linux -- are there if you want to run the same distribution for years and years.
But that's only true if you can stick with the relatively anemic selection of desktop packages available in the CentOS, Scientific Linux and, by extension, Red Hat repositories.
You soon hit a wall. Applications you use every day in Debian, Ubuntu and even Fedora are just not there.
For me those include the Audacity and Ardour audio editors and the OpenShot video editor (or ANY video editor, for that matter). For others -- and maybe for you -- it could mean Skype (if that's your thing, and it very well might be) or the VLC media player.
And then there's a buttload of codecs and other various (and) naughty multimedia bits that are available but often hard to find.
