Hello,
Does anybody know why we are still using %{?_isa} thing?
DNF/libsolv forcefully install 64bit package for any 32bit package in
transaction. So it is not possible to get 32bit package without 64bit
counterpart.
So then what's the reason of using %{?_isa}? Just some old cruft from yum era?
Can we drop it? Thoughts?
%{_isa} is there to express very real dependencies where plain NEVR is
ambiguous and insufficient. Just because dnf/libsolv/yum whatever might
do the right thing by heuristics when installing doesn't mean the
dependency is not there (think 'rpm -e <pkg>' for one)
Also history has shown over and over again that depsolver heuristics get
confused with multilib'ed package splits and things like partial push
with missing multilib arch gets pushed to repos.
