Package: coreutils Version: 5.97-5.3 Copying a file to a windows share mounted using the kernel cifs module in debian 4 causes the date stamps not to be preserved using cp -p , cp -a, cp --preserve=all . Under woody, this behaviour was not seen, and the date stamps were correctly preserved when requested. In conducting some research into this problem, I discovered this ubuntu bug report, however it relates to copy via nfs not cifs. However the behaviour is identical to that I am now seeing with debian 4. https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.15 /+bug/57317 Sadly, it appears that it is not just debian 4 that suffers with this issue. I have tried a gentoo system and that too has this behaviour. I don't know where the core issue lies. If the files are copied using ssh with switches to preserve dates, the files do preserve the dates. This leads me to believe the issue lies within the cp application or the fileutils/coreutils package.

But because the libc and the kernel are both involved and both are also different between the systems and because I have seen related issues there I am suspicious of them. There are multiple different ways to obtain and set file timestamp information. It is possible that scp is using a different system call than cp and therefore different behavior results. Bob
