I have my own local copies of the CentOS 5.3 x86_64 and i386 repos - and to save space, I ran 'hardlink' over the RPMS directories - however it found that a number of the i386 and noarch RPMS in the x86_64 tree were 'different' from the matching RPMS in the i386 tree. Out of the 1186 i386/noarch RPMS on the 5.3 x86_64 iso image, 222 are different from the matching i386/noarch RPMS from the i386 iso image The difference appears to be the 'Signature' date - the rest of the info from 'rpm -qi' appears identical. Most of these 'different' RPMS are ones that have been updated in 5.3 Is there a reason why these RPMS have a different signature date? Not a major issue ... Thanks James Pearson
