[opensuse-packaging] Checking overlapping files
Hi! As I recall, on Ubuntu you could not install two packages which include overlapping files. Here on OpenSUSE it is possible, and there is even no warning: the files just go overwritten. When one package is removed the files are removed as well even if used by the other package. I do not know if this behavior is good or not but is there a possibility to check the overlapping files in the build time so to know that your package does not have common files with other ones? -- To unsubscribe, e-mail: opensuse-packaging+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-packaging+help@opensuse.org

I know that dpkg comlpains about it, but I'm not sure if apt/aptitude deal with overlapping files when solving package dependencies.

No, that's not true. Rpm knows if a file is shared between multiple package, it will only be deleted if the last package that owns it gets removed.

It's not possible to check this at build time as you don't know the other packages of the repo. It's possible to check this at repository creation time (i.e. "publish" time), but then you only know that no other package in the repo overwrites the files, but you don't know if there's a conflict with packages from other repos.

Surely the package that contains the same files as an installed package should conflict or provide the files or at least depend on the package for the files?
