Indeed, you should use cp -p or rsync -a as this copies permissions and users. If you then also copy /etc/passwd and /etc/group you'll have a matching set of permissions/users/groups.Sjoerd Hardeman:Why not just copy /etc, /home, /root and /var, and make sure you do not follw symlinks in copying. That should do.Not quite. This might lead to problems when UIDs have changed. Some packages (say, Apache) create new users and files which belong to these users. Even if you install the same set of packages on a new system, you have no guarantee that these users are created in the same order (and hence with the same UIDs/GIDs). My approach would be to set up every service manually by copying the relevant config files and checking whether they need any customization (hostname, IP addresses come to mind). I give in that's very labour-intensive, but I cannot think of a better way (in terms of reliability).
