dpkg-divert(1) dpkg suite dpkg-divert(1)NAMEdpkg-divert - override a package's version of a file
SYNOPSISdpkg-divert [option...] command
DESCRIPTIONdpkg-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.
--listpackage file
Print the name of the package that diverts file (since dpkg
1.15.0). Prints LOCAL if file is locally diverted and nothing
if file is not diverted.
--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.
EXIT STATUS
0 The requested action was successfully performed.
2 Fatal or unrecoverable error due to invalid command-line usage,
or interactions with the system, such as accesses to the
database, memory allocations, etc.
ENVIRONMENT
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.
FILES
/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.
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:
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
