RHEL 7 released

Red Hat has sent out a suitably buzzword-laden press release announcing the availability of Red Hat Enterprise Linux 7. "Bare metal servers, virtual machines, Infrastructure-as-a-Service (IaaS) and Platform-as-a-Service (PaaS) are converging to form a robust, powerful datacenter environment to meet constantly changing business needs. Answering the heterogeneous realities of modern enterprise IT, Red Hat Enterprise Linux 7 offers a cohesive, unified foundation that enables customers to balance modern demands while reaping the benefits of computing innovation, like Linux Containers and big data, across physical systems, virtual machines and the cloud – the open hybrid cloud."

Darn the luck... I have some older hardware (HP ProLiant DL380 G5) I wanted to install it on but alas the HP CCISS driver has been removed and the installer doesn't see any hard disks. :(

I guess I'll have to keep those at RHEL6 and try some of my newer hardware.

Put "hpsa.hpsa_allow_any=1" on kernel commandline.

ISTR that RHEL is one thing blamed for holding python3 adoption back. Is RHEL 7 the first to support python3? What version(s) of python are available with it?

I believe it is Python 2.7

With Red Hat's Software Collections (SCL) 1.0 and 1.1, Red Hat added newer versions of several things as options. So one can easily have the system python (say 2.whatever on RHEL6) side-by-side with python 3.whatever installed under /opt/rh/. They provide multiple versions of php, ruby, python, perl, and add a few things like nodejs, mariadb, etc.

Now to answer your question as to what the default version of python is in RHEL7... according to the RHEL 7 release notes:

"Red Hat Enterprise Linux 7 includes Python 2.7.5, which is the latest Python 2.7 series release. This version contains many improvements in performance and provides forward compatibility with Python 3."

And I'm sure once SCL is available for RHEL 7, additional devel stack options will be available.

Hmm, that's not actually true as of November last year when 2.7.6 was released (and 2.7.7 was released in May).

Python 3 will need to be the default in Fedora before it ever becomes the default in RHEL. There's some Fedora/RHEL-specific packages that still need to be up-ported, but the real blocker is all the other upstream Python packages that need to be up-ported before Fedora can switch the default.

What do you mean by the default? Is anyone seriously thinking about python == python3? That would break a lot of third party programs...

Well no. That's what Arch did. The Fedora plan is different

There also seems to be some confusion over the release of the SPRM packages for RHEL 7. Supposedly Red Hat's FTP site has a README that refers to git.centos.org and people have been asking the CentOS folks what's going on. The CentOS folks have told everyone to ask the Red Hat guys what's going on but that there is a CentOS wiki page that explains how to use the git.centos.org system to grab sources and construct SRPMs from it if desired.

It sounds to me like the CentOS guys know exactly what is going on but they aren't allowed to say because someone from Red Hat should be making that announcement.

I think overall it is going to be good thing... that the source for RHEL will be available and trackable via git... but in the short term... not being able to easily download SRPM files from ftp.redhat.com is a big change... if indeed that change has happened. Say, where is the announcement? Or is the README all the announcement we are going to get.

Current sources for Red Hat Enterprise Linux 7 have been moved to the

I wouldn't put to much speculation in who knows what and who has been ordered to do anything.

This is the first time ever that Redhat had made a major release with CentOS as part of their organization. There is bound to be some confusion going on and people are being conservative in what they are going to talk about in public.

It will be interesting to see just how long before CentOS 7 comes out. Previous delays between CentOS and Redhat releases almost ended up being a deal breaker for the company I work at. We are not going to be willing to spend the money on Redhat licenses for every single system and having to support multiple versions of OSes is a significant burden while it was beginning to be increasingly difficult to run order versions of everything. Ubuntu LTS started coming up in discussions more and more. It would be easier in a lot of ways to simply switch to a different OS.

So hopefully better release coordination between CentOS and Redhat will be forthcoming.

If that happens and combined with the 'Software collections' it can be a huge win. This is interesting since it more closely resembles what we have to do to make sure that the application developers get the arbitrary dependencies they desire. Although I haven't even started looking at it closely it seems promising. I was leaning along the lines of abandoning rpms altogether for our in-house apps and just using something like Nix package management on top of Redhat since decoupling the package management system from the OS has turned out well for other things I've played around with. :/

At the very least people who have had problems with running the latest and greatest versions of PHP, python, or ruby should have a much easier time now on CentOS/Redhat.

What you describe makes perfect use case for docker. Given that RHEL 7's docker integration is big part of the release, I'm sure CentOS 7 will have that too. It is going to be along the lines of http://www.projectatomic.io/ and rpm-ostree.

Thanks. Docker is certainly interesting to us.

One thing we (I work for Red Hat) managed to do better this time is that there is actually alive EPEL-7 from the start (we have started to develop it with RHEL-7 Beta).

Concerning python. My machine says

matej@wycliff: ~$ rpm -q python
python-2.7.5-16.el7.x86_64
matej@wycliff: ~$

And yes, I believe that the main culprit for non-python-3 is anaconda and other essential Python programs on which whole distro stays. We don't have python3 anaconda AFAIK.

Because this also requires to port all the needed library, and make sure they all work fine. That's doable, but take a rather long time,since once you ported, you need to maintain the version 2 and the version 3 for a time. Which mean more ressources for testing, etc, etc.

http://seven.centos.org/2014/06/getting-the-sources-for-c... suggests that its git. Implicitly, build your own srpms, with recognition that this is change in workflow.
