Package: dpkg Version: 1.15.7.2 Severity: wishlist File: /usr/bin/dpkg-divert
Hi, it would be nice if dpkg-divert supported updates to the diversions, so one can change the --divert name or the --package owning the diversion directly through a single dpkg-divert call as in the following example. There is 'some' package providing an awful version of /the/file which was previously diverted by the package 'foo' to provide a much better version of /the/file. But now 'foo' has been renamed to 'bar' (or at least /the/file moved from 'foo' to 'bar') and now the package 'bar' has to take over the diversion. 'bar' would do the following in it's preinst: dpkg-divert --update # example new subcommand --rename # move around things in the file system if neccessary --old-package foo # the package that currently own the diversion --package bar # the new package that shall own the diversion --old-divert /the/file.not-foo # file from someone else is currently there --divert /the/file.not-bar # file from someone else should be here in the future /the/file # our much better file Of course the arguments to --old-package and --new-package must match the database. If either --old-package or --old-divert is omitted, only change the property where there is an --old-* parameter while the other must match the current database. Eventually the --update option could be combined with --add so that it either creates the diversion if there was none previously or migrates it. Packages doing this need to ensure proper versioned Conflicts/Replaces (Breaks/Replaces will probably be not enough) so that up- and down-grade paths work.
