File diversions are a way of forcing dpkg(1) not to install a file
into its location, but to a diverted location. Diversions can be used
through the Debian package scripts to move a file away when it causes a
conflict. System administrators can also use it to override some pack
ages configuration file, or whenever some files (which arent marked
as conffiles) need to be preserved by dpkg, when installing a newer
version of a package which contains those files.
dpkg-divert is the utility used to set up and update the list of diver
sions. It functions in three basic modes - adding, removing, and list
ing diversions. The options are --add, --remove, and --list, respec
tively. Additionally, it can print out the real name for a diverted
file with --truename. Other options (listed below) may also be speci

This means, that there are no exceptions, and whatever package
is installed, the file is diverted. This can be used by an admin
to install a locally modified version.

Actually move the file aside (or back). dpkg-divert will abort
operation in case the destination file already exists.

Output program name and version and exit successfully.
When adding, default is --local and --divert .distrib. When
removing, --package or --local and --divert must match if specified.
Directories cant be diverted with dpkg-divert.
Care should be taken when diverting shared libraries, ldconfig(8) cre
ates a symbolic link based on the DT_SONAME field embedded in the
library. Because ldconfig doesnt honour diverts (only dpkg does), the
symlink may end up pointing at the diverted library, if a diverted
library has the same SONAME as the undiverted one.
To divert all copies of a /usr/bin/example to /usr/bin/example.foo,
i.e. directs all packages providing /usr/bin/example to install it as
/usr/bin/example.foo, performing the rename if required:
dpkg-divert --divert /usr/bin/example.foo --rename /usr/bin/example
To remove that diversion:
dpkg-divert --rename --remove /usr/bin/example
To divert any package trying to install /usr/bin/example to
/usr/bin/example.foo, except your own wibble package:
dpkg-divert --package wibble --divert /usr/bin/example.foo --rename
To remove that diversion:
dpkg-divert --package wibble --rename --remove /usr/bin/example

tem. It is located in the dpkg administration directory, along
with other files important to dpkg, such as status or avail
Note: dpkg-divert preserves the old copy of this file, with
extension "-old", before replacing it with the new one.
