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 \fBdpkg\fP, when installing a newer version of a package which +contains those files. +.sp +.SH COMMANDS +.TP +.RB [ \-\-add "] \fIfile\fP" +Add a diversion for \fIfile\fP. +The file is currently not renamed, see \fB\-\-rename\fP. +.TP +.BI \-\-remove " file" +Remove a diversion for \fIfile\fP. +The file is currently not renamed, see \fB\-\-rename\fP. +.TP +.BI \-\-list " glob-pattern" +List diversions matching \fIglob-pattern\fP. +.TP +.BI \-\-listpackage " file" +Print the name of the package that diverts \fIfile\fP (since dpkg 1.15.0). +Prints LOCAL if +\fIfile\fP is locally diverted and nothing if \fIfile\fP is not diverted. +.TP +.BI \-\-truename " file" +Print the real name for a diverted file. +. +.SH OPTIONS +.TP +.BI \-\-admindir " directory" +Set the administrative directory to \fIdirectory\fP. +Defaults to «\fI%ADMINDIR%\fP». +.TP +.BI \-\-instdir " directory" +Set the installation directory, which refers to the directory where +packages get installed (since dpkg 1.19.2). Defaults to «\fI/\fP». +.TP +.BI \-\-root " directory" +Set the root directory to \fBdirectory\fP, which sets the installation +directory to «\fIdirectory\fP» and the administrative +directory to «\fIdirectory\fP\fB%ADMINDIR%\fP» (since dpkg 1.19.2). +.TP +.BI \-\-divert " divert-to" +\fIdivert-to\fP is the location where the versions of \fIfile\fP, as +provided by other packages, will be diverted. +.TP +.B \-\-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. +.TP +.BI \-\-package " package" +\fIpackage\fP is the name of a package whose copy of \fIfile\fP will not +be diverted. i.e. \fIfile\fP will be diverted for all packages except +\fIpackage\fP. +.TP +.B \-\-quiet +Quiet mode, i.e. no verbose output. +.TP +.B \-\-rename +Actually move the file aside (or back). \fBdpkg\-divert\fP will abort operation +in case the destination file already exists. +This is the common behavior used for diversions of files from the +non-\fBEssential\fP package set (see \fB\-\-no\-rename\fP for more details). +.TP +.B \-\-no\-rename +Specifies that the file should not be renamed while adding or removing the +diversion into the database (since dpkg 1.19.1). +This is intended for diversions of files from the \fBEssential\fP package set, +where the temporary disappearance of the original file is not acceptable, as +it can render the system non-functional. +This is the default behavior, but that will change in the dpkg 1.20.x cycle. +.TP +.B \-\-test +Test mode, i.e. don't actually perform any changes, just demonstrate. +.TP +.BR \-? ", " \-\-help +Show the usage message and exit. +.TP +.B \-\-version +Show the version and exit. +. +.SH EXIT STATUS +.TP +.B 0 +The requested action was successfully performed. +.TP +.B 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. +. +.SH ENVIRONMENT +.TP +.B DPKG_ROOT +If set and the \fB\-\-instdir\fP or \fB\-\-root\fP options have not been +specified, it will be used as the filesystem root directory +(since dpkg 1.19.2). +.TP +.B DPKG_ADMINDIR +If set and the \fB\-\-admindir\fP or \fB\-\-root\fP options have not been +specified, it will be used as the \fBdpkg\fP data directory. +.TP +.B DPKG_MAINTSCRIPT_PACKAGE +If set and the \fB\-\-local\fP and \fB\-\-package\fP options have not been +specified, \fBdpkg\-divert\fP will use it as the package name. +.TP +.B DPKG_COLORS +Sets the color mode (since dpkg 1.18.5). +The currently accepted values are: \fBauto\fP (default), \fBalways\fP and +\fBnever\fP. +. +.SH FILES +.TP +.I %ADMINDIR%/diversions +File which contains the current list of diversions of the system. It is +located in the \fBdpkg\fP administration directory, along with other files +important to \fBdpkg\fP, such as \fIstatus\fP or \fIavailable\fP. +.br +Note: \fBdpkg\-divert\fP preserves the old copy of this file, with extension +\fI\-old\fP, before replacing it with the new one. +. +.SH NOTES +When adding, default is \fB\-\-local\fP and \fB\-\-divert\fP +\fIoriginal\fP\fB.distrib\fP. When removing, \fB\-\-package\fP or +\fB\-\-local\fP and \fB\-\-divert\fP must match if specified. + +Directories can't be diverted with \fBdpkg\-divert\fP. + +Care should be taken when diverting shared libraries, \fBldconfig\fP(8) +creates a symbolic link based on the DT_SONAME field embedded in the library. +Because \fBldconfig\fP doesn't honour diverts (only \fBdpkg\fP does), +the symlink may end up pointing at the diverted library, if a diverted +library has the same SONAME as the undiverted one. +. +.SH EXAMPLES +To divert all copies of a \fI/usr/bin/example\fR to \fI/usr/bin/example.foo\fR, +i.e. directs all packages providing \fI/usr/bin/example\fR to install it as +\fI/usr/bin/example.foo\fR, performing the rename if required: +.HP +dpkg\-divert \-\-divert /usr/bin/example.foo \-\-rename /usr/bin/example +.PP +To remove that diversion: +.HP +dpkg\-divert \-\-rename \-\-remove /usr/bin/example + +.PP +To divert any package trying to install \fI/usr/bin/example\fR to +\fI/usr/bin/example.foo\fR, except your own \fIwibble\fR package: +.HP +dpkg\-divert \-\-package wibble \-\-divert /usr/bin/example.foo \-\-rename /usr/bin/example +.PP +To remove that diversion: +.HP +dpkg\-divert \-\-package wibble \-\-rename \-\-remove /usr/bin/example +. +.SH SEE ALSO +.BR dpkg (1). |
