Exactly this is the reason why it has to be mapped to the new file. Given you have a link "lib -> originallib" and now install "newlib", you somehow have to modify the link "lib" to point to "lib -> newlib" > The symlinks-1.0.rpm is upgraded with somethink like a > rpm -U symlinks-1.1.rpm > whereas the file is provided in a completely_different-1.0.rpm So to patch OOo you'll always have to install/update two packages? The symlink-rpm and a real-patch-rpm? So a symlink-package would be part of the initial install as well? And that symlink-rpm will always "hardcode" the symlink to the file from the real-patch-rpm? > >* may need some work in OOo to make it work with symlinked components > > you probably don't want to have all files symlinked as this clutters > your installation. True, but see the Help and images.zip Not having those as links mean either: * no updates possible or * those modules have to be yet in another package. > >Pros: > >* no command-line parameter to force the installation necessary > >* can tell whether a patch is installed by doing a ls /path/to/OOo > >* package can be uninstalled w/o problems (when original file is not > > removed) > > when removing the package you need to reinstall the old symlink package. Hmm. Downgrading requires a rpm-commandline switch.. What I was thinking of is a postuninstall script that points the link back to the original file - but if patches are always done using two packages... > >"just-replace-the-file"-method: > >Cons: > > * this is not much better than installing just the file by any random > installation mechanism I'd not say that. You can still use rpm to query where the file came from (you can't do this by copying the files by hand) And even more important: You can check whether the patch is already installed (by querying for the patch-package). You can't do that with any random method. > [...] ciao Christian -- NP: Metallica - Turn The Page --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
