Dear Maintainer, *** Reporter, please consider answering these questions, where appropriate *** = What led up to the situation? = Attempting to reinstall 'chrony' package due to my misapplied file ownership and permission settings toward /run/chrony and /etc/chrony/ = What exactly did you do (or not do) that was ineffective = I ran: apt purge chrony And found all my customized chrony drop-in configuration files in /etc/chrony/conf.d subdirectory having been deleted by the purge as well. I was half-expecting the purge only to delete what they installed and to let me know that some 'straggling' files were left behind as the dpkg usually do. = What was the outcome of this action? = Lost all my customized settings. Of course, I had backup; but is this really expected of 'purge'? = What outcome did you expect instead? = I kinda expected my customized drop-in config files under /etc/chrony/conf.d to remain intact (or at least renamed at the next occurance of 'apt install chrony' time.
