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