Fixes = These updates bring the following fixes: 1. Add CentOS-5 image, with selinux patch (thanks to Dan Walsh and Miroslav Grepl!) 2. CentOS-7 image includes a fakesystemd package instead of the distro provided systemd. This should resolve a number of the udev and/or pid-1 errors users were seeing. This package is only useful for docker, and WILL break other installs. 3. Images now contain a new file, /etc/BUILDTIME, to reference when the image was created/published. 4. Includes recent updates current to 20140902 Additional Information == For detailed information or to see the code differences used in building the images, please see https://github.com/CentOS/sig-cloud-instance-build -- Jim Perrin The CentOS Project | http://www.centos.org twitter: @BitIntegrity | GPG Key: FA09AD77 -- ___ CentOS-announce mailing list centos-annou...@centos.org http://lists.centos.org/mailman/listinfo/centos-announce End of CentOS-announce Digest, Vol 115, Issue 5 *** ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

By "logically" removing the failed device, you free up /dev/sdb (that just failed) to then use that again for the replacement drive. In all my cases the new drive goes in the same slot and through experience the new drive's device name has been the same as what I removed.

No, I'm still buying Dell desktops. I gave up on their rackmount boxes (with Dell you don't have flexibility of choice of your preferred, say, RAID cards: step left, step right and you are shot ;-). I get rackmount ones assembled by small company (companies) and about 1/2 of cost of similar hardware from Dell. Those are for the most part based on Tyan barebones. And during last at least decade I never had a "must to" flash newer BIOS situation with any of those boxes. If I ever flashed new BIOS, it was only once before I put the box in production. Of course, I flashed BIOS of my laptop (after unsoldering EPROM, dumping original BIOS content, editing the darn thing with hex editor, flashing it on new EPROM chip, and then sticking it into socket I soldered to laptop system board in place of EPROM chip), but that is different. The World will not stop spinning if my laptop stays dead for a couple of days, or weeks or forever. Any of the servers. - its way different.

[CentOS] installing Desktop faster

Re: [CentOS] installing Desktop faster
FreeBSD base system is installed similarly to what you suggest: just by unpacking a few tgz files containing it. This, however, only comprises base system; the rest necessary for workstation (such as Xwindow system, office suites, etc) are to be added separately. However, once the system is installed it would be a nightmare to update "one single enormously large" package (as someone already mentioned). Luckily, there is nice equivalent of what you would like standard Desktop installation would be, or anything else which you can tweak to your needs once and then install that tweaked system with one go on as many boxes as you wish. It is called "kickstart". Even better: RedHat (and CentOS) have more or less preconfigured set of stuff to install (minimal, Desktop, server, Development workstation,...) you can just use one of them in graphic installer and voila, you will have it installed with minimal brain effort.

I agree that flashing the firmware should be a rare event, but expecting the rate to be exactly 0 is an unreasonable expectation. I have had to flash a BIOS once, and a BMC once, in about 10 years of buying server hardware. (Yes, flashing a BMC probably wouldn't brick a box, but it'd brick getting a remote console, which for me is almost as serious.) I consider that an acceptable bug rate. Flashing a RAID controller is actually more frightening to me--flashing the BIOS isn't likely to hose your data, but an undetected bad flash on a RAID controller could. Sadly my flash rate of my controllers is slightly higher than my BIOS flash rate. --keith -- kkel...@wombat.san-francisco.ca.us ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Yes Samba4 is capable of working as a AD domain controller and more.

You did have nice thing before you flashed, which alas was different hardware from what you needed. You flashed different version to modify hardware. And after that the hardware was exactly what you needed it to be. And from this point on you don't need to flash it, unless you decide to change its functions to what they were with original firmware. This whole thing is way different from what I originally was displeased (i.e. the "necessity" to apply updates to firmware to fix the thing that appears to be broken with older crappy version of firmware). So: LSI still is in my list of great hardware manufacturers. (Even though my favorite is 3ware, I forgot to mention one other good one: areca, whose place will be after lsi in my book). And I don't care how hard it is to flash LSI card (which you had to do _before_ you placed it into production). In worst case scenario you could hire someone to do it for you. After doing it yourself you can become extremely proud of yourself: now you know that you are worth of your salary. But certainly you knew it before that ;-) Valeri > > > -- > john r pierce 37N 122W > somewhere on the middle of the left coast > > ___ > CentOS mailing list > CentOS@centos.org > http://lists.centos.org/mailman/listinfo/centos > Valeri Galtsev Sr System Administrator Department of Astronomy and Astrophysics Kavli Institute for Cosmological Physics University of Chicago Phone: 773-702-4247 ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] SAMBA as AD DC
It would appear the samba4 DC isn't available for C7 just yet. "As Fedora and RHEL are using MIT Kerberos implementation as its Kerberos infrastructure of choice, the Samba Active Directory Domain Controller implementation is not available with MIT Kereberos at the moment."
