dpkg-divert - override a package’s version of a file |
|
dpkg-divert [options] [--add]
<file> |
|
File ‘diversions’ are a way of forcing dpkg 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. dpkg-divert is the utility used to set up and update the list of diversions. It functions in three basic modes - adding, removing, and listing diversions. The options are --add, --remove, and --list, respectively. Additionally, it can print out the real name for a diverted file. Other options (listed below) may also be specified. |
|
--admindir <directory> |
|
Set the dpkg data directory to <directory> (default: /var/lib/dpkg). |
|
--divert <divert-to> |
|
<divert-to> is the name used by other packages’ versions. |
|
--help |
Output the version and the short usage instructions, and exit successfully. |
|
--local |
|
Specifies that all packages’ versions are diverted. |
|
--package <package> |
|
<package> is the name of a package whose copy of <file> will not be diverted. |
|
--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. |
|
--version |
|
Output program name and version and exit successfully. |
|
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), if a diverted library has the same SONAME as the undiverted one the symlink may end up pointing at the diverted library. |
|
/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’. |
|
dpkg(8). |
