[CentOS] Missing dependency in C6 ISO
Greetings, I had downloaded c6 64 bits ISO, selected all packages to be installed. One dependency warning relating to Emacs appeared. I chose to continue. Unfortunately I was multitasking and did not note down the package name Twice this issue appeared -- first time around aborted install due to power cut. Did anybody else face this situation? Also is there a better way with just DVDs and not LAN to select all package install. (no Kickstart, NFS server etc.) I have the ISO images though. /ducks I know no sysadmin installs everything on a centos box...

The distribution is build by upstream so packages within a release do not conflict with one another. An installation including every single packages should not be a problem. If the original poster is seeing dependency issues with the ISO install he should probably take a note of what package it is that is missing from that particular ISO so the CentOS team can look into it and correct the spin if needed.

The idea actually came from Dell. It's frequently described as a method to prevent the device name from changing during a reboot, but that was already in place. What biosdevname does is make names *predictable* on Dell systems. It shouldn't be enabled anywhere else. As you stated, the documented method of turning the feature off is to add biosdevname=0 to the boot configuration (which means rebooting). http://fedoraproject.org/wiki/Features/ConsistentNetworkDeviceNaming ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I have a hard time imagining that you'd get useful information from cross-posting this to the FreeBSD and CentOS lists. Their implementations of filesystems are completely different. If you use a CentOS NFS server, I'd recommend ext4. In benchmarks, I often see XFS perform better than ext4 in specific tests. JFS rarely does well. However, the last time I used XFS was for a system running Zoneminder. Benchmarks let us to believe that XFS would be a better filesystem, but in our actual implementation it couldn't keep up. The application couldn't delete data quickly enough when the volume was nearly full, so the volume would fill up and the system would fail. We only got it working reliably after switching to ext4. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

There is a newer version of openmpi that obsoletes that rpm and yum can handle it, but anaconda can not handle that obsolete. Because of that, it breaks the installation. This issue should be taken care of on the 6.4 ISOs.
