[Fedora-packaging] RPM doesn't conflict

[Nelson Manuel Marques]

Hi all,

I would like to clear a doubt if possible regarding the installation of RPM's and potential conflicts. Here's somehow a twisted use case:

 1) 2 RPMs: foobar-1.0.noarch.rpm and foobar-2.0.noarch.rpm
 2) Both RPMs have exactly the contents: %{_sysconfdir}/foobar.conf
 3) The contents of the file foobar.conf are the same in both RPM's, it has a single line with: Hello World!

Now, if I do:

 # rpm -ivh foobar-1.0.noarch.rpm && rpm -ivh foobar-2.0.noarch.rpm

Both RPMs install perfectly. Please notice I'm doing '-i' and not '-U'. Is this the intended behavior of the RPM ? Shouldn't it return a conflict because the file is already installed ?

If I change the contents of the file, so that both RPM's have the same file with different contents (which makes a different hash), the conflict does exist.

Anyone could clarify to me why one conflicts (which I believe to be the intended behavior using '-i') and if the files are exactly the same they don't conflict and it allows install...

Thanks.
