It is more of an impact for yum-3 compatibility as yum4/dnf is being considered in the RHEL7/CentOS7 userspace environments as described at https://blog.centos.org/2018/04/yum4-dnf-for-centos-7-updates/ > > > > Currently yum version 3 and what the proof-of-concept project is calling yum4 work very well together side by side. Users can safely switch back and forth. The major problem is yum/dnf histories being different and the rpmdb checksum difference is a blocker for resolving the history compatibility. > > > > So think of this as an effort to bring package management parity between Fedora, RHEL 7, & CentOS7, as the latter two still have a long life ahead of them. > > > > Is there a reason why we can't change YUM to match the DNF behavior? > IMO, the YUM behavior is nonsense and isn't even a valid package > identifier. Actually E:N-V-R.A is yum-ism no one else understand while N-E:V-R.A is correct rpm format. $ rpm -q bind-libs bind-libs-9.9.4-61.el7.x86_64 $ rpm -q 32:bind-libs-9.9.4-61.el7.x86_64 package 32:bind-libs-9.9.4-61.el7.x86_64 is not installed $ rpm -q bind-libs-32:9.9.4-61.el7.x86_64 bind-libs-9.9.4-61.el7.x86_64 So if you want make world a better place stick with current dnf format. -- Michael Mráka System Management Engineering, Red Hat _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx/message/KXLUGD7446XWI4TS2ITKQ2JPUAGHEF5S/
