Hi, On our cluster with CentOS 5.5, I have a little problem with a script for infiniband (this problem: http://web.archiveorange.com/archive/v/NUQmuN84gd3D31Fdl8PU). So the fix a very easy. But what will yum/RPM do during the next update ? Will it overwrite the file ? Will it write on display that the file was modified by an user (as under debian) ? Thx a lot, Best regards, Guillaume
