I've already got a female to worry about. Her name is the Enterprise.

Yesterday new CentOS kernels was released and could be updated with yum update. I did that on 3 systems and none of them worked afterwards.

The first system is the machine that runs this blog. It runs Xen kernel with two virtual system.Luckily the webserver and database runs in Dom0. After update the system did not start, it seems like the Xen kernel is broken, so now I run non-Xen kernel.

The second system is my op5 Monitor system that monitor my environment. That changed the default kernel to Xen and that was broken, after chenged boot kernel to the non-Xen it works again.

The third machine is my fileserver, with a couple of disks. Two of the filesystems are XFS, and the new kernel did not have support for XFS so my large file systems could not be mounted. So I started the old kernel with XFS support.

This is not an acceptable behavior of an enteprise operating system.
