dpkg-divert - override a package’s version of a file
dpkg-divert [option...] command
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.
- [--add]
file
- Add a diversion for file.
- --remove file
- Remove a diversion for file.
- --list
glob-pattern
- List diversions matching glob-pattern.
- --listpackage file
- Print
the name of the package that diverts file. Prints LOCAL if file is locally
diverted and nothing if file is not diverted.
- --truename file
- Print the real
name for a diverted file.
- --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.
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.
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 /usr/bin/example
To remove that diversion:
- dpkg-divert --package wibble
--rename --remove /usr/bin/example
-
- DPKG_ADMINDIR
- If set and the
--admindir option has not been specified, it will be used as the dpkg data
directory.
- DPKG_MAINTSCRIPT_PACKAGE
- If set and the --local and --package options
have not been specified, dpkg-divert will use it as the package name.
- /var/lib/dpkg/diversions
- 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.
dpkg(1).
