No action is actually taken. -P foo, --package foo Don't follow dpkg-divert diversions by package foo. -v, --verbose Make the script verbose --three-way Register this file in the cache, and turn on the diff3 option allowing the merging of maintainer changes into a (potentially modified) local configuration file. ) --state-dir bar Set the state directory to bar instead of the default '/var/lib/ucf'. Used mostly for testing. --debconf-ok Indicate that it is ok for ucf to use an already running debconf instance for prompting. --debconf-template bar Specify an alternate, caller-provided debconf template to use for prompting. Usage: $progname -p destination -p, --purge Remove any reference to destination from records By default, the directory the new_file lives in is assumed to be the src-dir, which is where we look for any historical md5sums.

This code is in use since many months in the aide package and seems to work "well enough". See aide-common's maintainer scripts for usage examples. The package ships the current version of all config files in /usr/share/aide-common/config, and handles all of them in a single call of handle_all_ucf_files /usr/share/aide-common/config /etc. The code expects that the first parameter of handle_all_ucf_files is a pointer to the directory structure, and handle_all_ucf_files rebuilds that structure in the target directory. See the aide-common package for reference. This directory also contains a test suite so that the correct behavior of the function can be verified. Call ./testsuite as root. Sorry, the test suite needs root privileges and uses the ucf database of the host system.
