While I have used xfs for years on SuSE systems, and have it on
several CentOS 5.1 systems, I will probably not use it on new
installations as ``yum update'' on the CentOS 5.1 systems now
fails saying it cannot update kmod-xfs.
I prefer to keep things close to the LCD to avoid issues with
extensions that may not be updated in a timely manner.
