Is the whole
yum update transactional or is every resolved update individually?
yum update detects
Bar need to be updated, and
Bar fails because it now collides with installed package
Foo get updated? Does the transaction include
yum update Foo and
yum update Bar independent of each other, or
Foo doesn't get updated by default, is there an easy way to make it get updated regardless of failures of other parts of system update?
