Yes - if someone writes to /var after the file was copied, this change will be lost. You can make the window where such a change would be lost smaller by running rsync twice: # rsync -av /var/* /new_var # rsync -av /var/* /new_var where the second command should only take a few seconds (rather than very long, if, for example, /var/www is large). It might furthermore be helpful to remound /var read-only before the procedure and shut down as many services as possible – if nothing writes to /var, no data will be lost :) Best, Claudius -- Please don’t CC me. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
