## XXXvlab: a lot of this intelligence should be moved away into ## ``logrotate`` charm ## ## Issues: ## - relation-joined will execute first log-rotate charm part of the ## relation, which is not what we want here, as we need to send ## default value for the creation of the config file on the server ## part. ## - we need to send the directory it seems, otherwise, docker will ## create directory when the log file is missing, and I'm not sure ## how processes will react when their file is moved out of their ## file-system scope when rotated (but I think there will be no ## issue here). ## The problem here is that we can't cleanly put all file in the ## same directory (and there are collision possible anyway). ## This means that if we want more than one target, we need ## sub-directories. ## - For this issue, we only fear the 'docker' run and mounting ## moment, and we are sure to run before, so we can make sure to ## ``touch`` the files. ## - can we move file that was been bound in a docker ? Well yes, ## but it won't change place in the docker:( ... I guess you need ## to reload the docker and the binding to work. ##
