Montana Enterprise Linux 7?
If you didn't hear the news, Red Hat released Red Hat Enterprise Linux 7 on Tuesday, June 10th. I've done three installs so far at work... and have been reading through their wonderful documentation. I'm really digging the newer versions of things and systemd... yes, especially systemd. No, no, really!
As you also probably know, Red Hat sponsors the CentOS Project now... and they are working hard on getting CentOS 7 done. Andrew from the BillingsLUG predicts CentOS 7 will be out within two weeks of RHEL 7... so that would be by June 24th. My guess is 6 weeks... which would be by July 22nd. If they don't make it in 6 weeks, my next guess is August 10th, because that's my 50th birthday.
Anyway. So yeah, the CentOS Project has been hard AND they have been, unlike in the past, doing everything out in the open... transparency it is called. Yesterday they announced they had the packages building. Then someone on the centos-devel mailing list said they had a Docker CentOS 7 container image. I gave that a try. Then the centos-devs said they had the first build attempt completed although they have NOT gone through all of the packages yet and removed Red Hat's branding... so it's a very preliminary build. Then they announced they had a network install CD (~ 341MB). I gave that a try and it worked great.
Then I decided I wanted to work on my own remix if possible. I used reposync to download all of the packages... and wget to get the handful of other dirs/files in the install tree. Then I made a KVM virtual machine via a network install pointed at my own copy of the tree. Then I added the livecd-creator package that one CentOS developer ported from Fedora. Then I installed fedora-kickstarts from Fedora 19... and hacked on their KDE LiveCD kickstart until I had it building CentOS 7. The first build didn't go so well. For whatever reason, all of the GUI stuff was there except for Xorg. I was able to use that first install, get it going in text-only mode to figure out what packages I needed to add to my kickstart's package list to get X going. Bingo... only three additional lines although two of them had an asterisk in them.
It built. It booted. It installed. It booted and worked post-install. Not bad.
What does it contain? Well, I'm a KDE fan. EL7 only offers GNOME 3 and KDE anyway. So, it has KDE... but oddly they don't offer KDM (KDE Display Manager aka GUI login screen) so it uses GDM (GNOME Display Manager). While Red Hat defaults to the XFS filesystem in their install media (they don't have any Live media by the way, just install-only) livecd-creator would not build the .iso if I set the default to xfs... so I had to set it to ext4. So, the system you get from the live installer has ext4 partitions. While it is the KDE desktop I added some stuff that isn't KDE-specific... like Firefox, Libre Office, GIMP, and Inkscape. I didn't refer to the EPEL 7 repository in my kickstart so the first good build only includes stock packages. Later I'll probably add in EPEL and add some additional packages like tmux, x2goserver... and a few other sundry packages. Any suggestions?
I should have included some screenshots with this post but I'm too lazy and tired after spending about 6 hours working on this little project today. If you want to give it a try let me know and I can email you the URL to the .iso file. Oh, btw... the installed system does not include a working centos.repo file so after a fresh install is booted, one has to manually add one by creating a file named /etc/yum.repos.d/qa-nightly.repo. Put in it the following:
Then you can use yum to install anything else you'd like. I recommend you also add EPEL 7 (epel-release-7-0.1.noarch.rpm). Enjoy! MEL (Montana Enterprise Linux), kiss my grits!
Update: CentOS has since released Public QA LiveMedia of their own.
