## 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.
