Sounds a lot like Solaris containers of a decade ago.

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.

Yep. Or BSD jails before that.

Yeah, I have been doing some research for an upcoming screencast, and this type of idea is called Operating system-level virtualization [1], and there is a fairly good table with the various OS's and their take on OS-level virtualization. E.g. Solaris Containers, FreeBSD Jail, OpenVZ, HP-UX Containers, etc.

"All Java 7 packages (java-1.7.0-openjdk, java-1.7.0-oracle, java-1.7.0-ibm) in Red Hat Enterprise Linux 7 beta let you install multiple versions in parallel, similarly to the kernel." This sounds pretty convenient to me.

I don't think that this is new (other than 1.7 being the default now) unless they are using something other than alternatives: https://access.redhat.com/site/documentation/en-US/JBoss_Ent...

New to me :)

What I recall from a while ago is finding systems with just openjdk and having to install the 'official' version manually. That could have been Fedora though.

Earlier quoted context omitted.

As someone who uses CentOS 6 on the desktop, people really should take a look at this. For me, it's the only Linux desktop which I can find which is reliable and works out of the box with all my hardware.

Yes, I have CentOS 6 on a Thinkpad x200s with hard drive encryption enabled as my work machine. I find it stable and quite fast. I may leave that machine on CentOS 6 and put 7 on the 'play' laptop. My point was giving a choice of desktops is a new departure for Red Hat. Remember that they employ, or have employed, a number of the Gnome developers, and that I gather Red Hat has been a major sponsor of Gnome in the pas…

>> 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.
