NAME
dpkg-divert - override a package's version of a file
SYNOPSIS
dpkg-divert
[options]
command
DESCRIPTION
dpkg-divert
is the utility used to set up and update the list of diversions.
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 package's configuration
file, or whenever some files (which aren't marked as 'conffiles') need to be
preserved by dpkg, when installing a newer version of a package which
contains those files.
COMMANDS
[--add] file
Add a diversion for file.
--remove file
Remove a diversion for file.
--list glob-pattern
List diversions matching glob-pattern.
--truename file
Print the real name for a diverted file.
OPTIONS
--admindir directory
Set the dpkg data directory to directory (default: /var/lib/dpkg).
--divert divert-to
divert-to is the location where the versions of file, as
provided by other packages, will be diverted.
--local
Specifies that all packages' versions of this file are diverted.
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.
--package package
package is the name of a package whose copy of file will not
be diverted. i.e. file will be diverted for all packages except
package.
--quiet
Quiet mode, i.e. no verbose output.
--rename
Actually move the file aside (or back). dpkg-divert will abort operation
in case the destination file already exists.
--test
Test mode, i.e. don't actually perform any changes, just demonstrate.
--help
Show the usage message and exit.
--version
Show the version and exit.
NOTES
When adding, default is --local and --divert<original>.distrib. When removing, --package or --local
and --divert must match if specified.
Directories can't be diverted with dpkg-divert.
Care should be taken when diverting shared libraries, ldconfig(8)
creates a symbolic link based on the DT_SONAME field embedded in the library.
Because ldconfig doesn't 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.
EXAMPLES
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:
File which contains the current list of diversions of the system. It is
located in the dpkg administration directory, along with other files
important to dpkg, such as `status' or `available'.
Note: dpkg-divert preserves the old copy of this file, with extension
"-old", before replacing it with the new one.
