If this is in a maintainer script, just don't run ucf. If this is as an end user, you should have been asked a question had you modified the file -- and yes, you can recover the older version of the file. I want to preserve my configuration, so i would like to use ucf (or dpkg-divert) But maybe i don't understand the necessity of the ucf utility. If the file is not a conffile, does i need to use it? But, even if it is not a conffile, a upgrade can override it.? What i have done : My package install the files in /usr/share/site_configuration/.

I have created a package which manage some files with ucf BUT when i remove the package i would like to restore the files before the installation . I could rename the file package_file.conf.dpkg-old in package_file.conf in postrm script (remove) The dpkg.old file might not exist at that point ( the user might have gotten rid of it, for one thing). If you want to reliably do that, copy the file somewhere safe, and restore from your cached location later. Depending on the old file being around is risky. So i could: save the old configuration files (maybe in /usr/share/site_configuration_backup/.) My package install the files in /usr/share/site_configuration/. My postinst script use ucf to install them in the right place. On postrm or prerm (remove) , restore the backup files. (and on purge, purge the ucf stuff) Thank you for your recommendations...

The changes would be considered local by the next upgrade of the package you are modifying the configuration.
