Hopefully we will see some type of GUI to create containers and manage cgroups. The GUI for libvirt is called virt-manager: http://virt-manager.org/

It can be even more seamless and convenient than that with Systemd.

https://fedoraproject.org/wiki/Features/SystemdLightweightCo...

I’m not sure what Systemd version they’ll end up shipping though.

The best part about Systemd is that the default framework for launching and monitoring services is essentially LXC without the padding (extra PID0 etc). This means every service can benefit and there’s no need for the unnecessary abstraction (the container) and all the (mental not necessary performance) overhead that goes with it.

Needless to say, I’m quite excited about what is happening on Linux nowadays :)

64-bit ISO: ftp://ftp.redhat.com/pub/redhat/rhel/beta/7/x86_64/iso/rhel-everything-7.0-beta-1-x86_64-dvd.iso

Is this an 'open' beta or do you need a subscriber key? Just curious, I usually wait for CentOS for a desktop installation on a laptop

Anybody know if they have the new C++ toolchain that will allow Chrome to start working again?

Wow, XFS by default, is there any other distro that uses it by default? Makes me miss my old SGI machines...

I was struck by that too, and came here to make the same comment. Why do you suppose they went with XFS? Ext4 seems like the defacto file system these days, but I know a lot of people seem to prefer XFS for one reason or another. It's a surprise to me that RHEL decided to default too it. Anybody care to shed some light?

Dave Chinner's talk is great: http://www.youtube.com/watch?v=FegjLbCnoBw

This is very exciting. I know until it gets all the government certs and rubber stamps I won't be able to use it at work but if it is out the ball can start rolling as they say. Here is the list of all the detail (tech notes): https://access.redhat.com/site/documentation/en-US/Red_Hat_E... You can see updated and deprecated packages as well as issues so far in beta.

Which certs are most important these days for govt use? Or does it depend on which department you're going for?

FIPS 140-2, and Common Criteria (EAL) are the two most often checked in my area of work.

How long were the beta periods for RHEL 4, 5, 6? I know there's no commitment, but I'd like to tighten my vague idea of how long the beta period will be. Right now, I guess more than a day and less than a year.

Typically about 6 months, judging from the press releases announcing the public betas of 4, 5, and 6, and comparing to the GA release dates.

RHEL 4 beta: Sep 27, 2004 / GA: Feb 15, 2005

RHEL 5 beta: Sep 7, 2006 / GA: Mar 15, 2007

RHEL 6 beta: Apr 21, 2010 / GA: Nov 9, 2010

Can anyone explain a bit more about what happened to Red Hat? I'm about behind the history of this Distribution. Last time I read about it I found out that is paid and I never considered it, because of that. I'm using Slackware for most of my servers, but I don't know what is the target market or what is more special in Red Hat Enterprise.

The biggest reason to get RHEL is certification (assuming you don't need their tech support or updates). A number of third party vendors will only support one of the Enterprise Linux distributions (RedHat, Suse, Oracle Linux, etc). Now the technical differences between RHEL and, say Fedora, is that RHEL gives you a long time of getting bug / security fixes that are "minimally invasive", that is you can apply them and have a very good chance that your existing configuration and apps still work without a reinstall ore reconfiguration. (This is what is meant by "stability").

For personal use, you can get similar stability from either CentOS or Scientific Linux, although the bug fixes will lag behind Red Hat by a few days (although some critical updates have been released only a few hours after Red Hat).

>> giving a choice of desktops is a new departure for Red Hat Is it? I've only used RHEL on servers but I've used CentOS on my desktops and laptops for a long time with many re-installs - I've always seen the choice to use KDE as part of the base install.

Then I must be mistaken, thanks. I've tended to associate CentOS with Gnome, and I installed from live CD with a reduced package set. I still think it is significant that Red Hat are publicising the choices.

Yeah - Gnome was definitely the subtle default. IIRC correctly, the Gnome option is called "Desktop", and the KDE option was called "KDE" (or something like this). So unless you had a known preference, you'd end up with Gnome. Contrast this with openSuSE that has 2 specifically-named download options.

Exactly - if they support and test LXC now, and the market demands Docker a year into the lifecycle (RH generally don't add features between major releases, so it'd have to be worth it for them), it's still doable as it's a userspace addition.

Red Hat just added Docker to RHEL 6.5, so there's your example of them adding something mid-lifetime.

"Added" via EPEL and supported by redhat officially isn't the same thing.
