NAME
ucfr - Update Configuration File Registry: associate packages with configuration files
SYNOPSIS
ucfr [options] <Package> <Path to configuration file>
DESCRIPTION
Where Package is the package associated with the configuration file (and, in some sense,
its owner), and Path to configuration file is the full path to the location (usually under
/etc) where the configuration file lives, and is potentially modified by the end user.
This script maintains an association between configuration files and packages, and is
meant to help provide facilities that dpkg provides conffiles for configuration files and
not shipped in a Debian package, but handled by the postinst by ucf instead. This script
is idempotent, associating a package to a file multiple times is not an error. It is nor-
mally an error to try to associate a file which is already associated with another pack-
age, but this can be over ridden by using the --force option.
OPTIONS
-h, --help
Print a short usage message
-n, --no-action
Dry run. Print the actions that would be taken if the script is invoked, but take
no action.
-d [n], --debug [n]
Set the debug level to the (optional) level n (n defaults to 1). This turns on
copious debugging information.
-p, --purge
Removes all vestiges of the association between the named package and the configu-
ration file from the registry. The association must already exist; if the configu-
ration file is associated with some other package, an error happens, unless the
option --force is also given. In that case, the any associations for the configura-
tion file are removed from the registry, whether or not the package name matches.
This action is idempotent, asking for an association to be purged multiple times
does not result in an error, since attempting to remove an non-existent association
is silently ignored unless the --verbose option is used (in which case it just
issues a diagnostic).
-v, --verbose
Make the script be very verbose about setting internal variables.
-f, --force
This option forces operations requested even if the configuration file in consider-
ation is owned by another package. This allows a package to hijack a configuration
file from another package, or to purge the association between the file and some
other package in the registry.
--state-dir /path/to/dir
Set the state directory to /path/to/dir instead of the default /var/lib/ucf. Used
mostly for testing.
USAGE
The most common case usage is pretty simple: a single line invocation in the postinst on
configure, and another single line in the postrm to tell ucfr to forget about the associa-
tion with the configuration file on purge (using the --purge option) is all that is
needed (assuming ucfr is still on the system).
FILES
/var/lib/ucf/registry, and /var/lib/ucf/registry.X, where X is a small integer, where pre-
vious versions of the registry are stored.
/etc/ucf.conf
EXAMPLES
If the package foo wants to use ucfr to associate itself with a configuration file
foo.conf, a simple invocation of ucfr in the postinst file is all that is needed:
ucfr foo /etc/foo.conf
On purge, one should tell ucf to forget about the file (see detailed examples in
/usr/share/doc/examples):
ucfr --purge foo /etc/foo.conf
