Hello, I want to upgrade samba with minimal downtime, and do not want to have all build-libraries on the production server. So I compiled on another machine, and now want to replace the binaries in /usr/local/samba. However some of the subdirectories contain config files, which must be preserved. I assume these are: etc, private, var/lock, and var/locks. AD-DC also needs sysvol. Is this list correct, incomplete, too much? Thanks Klaus
