If I understood Honza correctly, he was objecting to this alias because it
would pull in DNS dependencies.

So I tried to add this Provides to freeipa-server-core package but I'm not
able to make this alias to work with DNF at all. With old Yum it pulls in
freeipa-server-dns instead of -core because the "Obsoletes" apparently has
higher priority than Provides. (No, "Provides" with explicit version does not
change anything.)

The only text I found about this is the advice 'do not do it' :-)

https://fedoraproject.org/wiki/Upgrade_paths_%E2%80%94_renaming_or_splitting_packages#Do_I_need_to_Provide_my_old_package_names.3F

In other words, I'm not able to make to make the alias freeipa-server working
with the second version of my patch.

Again, this problem is related only to  the second/alternative version of the
patch where freeipa-server package does not pull in DNS dependencies. "dnf
install freeipa-server" works with first version of my patch which pulls in
DNS depencies.


I'm more than happy to take advice how to fix that. For now I would say that
first version of the patch is okay. It will solve the upgrade and we can
remove the 'Requires' in the next release because it will not be necessary for
upgrade anymore.
