Description of problem: When using DNF as an engine to set up a Linux system (through an installer like DrakX or Anaconda, or through appliance image creation tools like livecd-tools or kiwi), it's not possible to get %_install_langs during initial bootstrap phases because the host rpm is used in that circumstance rather than the target rpm. In YUM, there's an "override_install_langs" option in yum.conf that can be used to do this, and this can also be passed via the command line to have YUM set this when it executes so that it's respected no matter which RPM is invoked. Can this please be added to DNF so that tools like appliance-creator, kiwi, etc. can leverage it? Version-Release number of selected component (if applicable): 3.1.0-1.fc29 Additional info: KIWI RFE for this: https://github.com/SUSE/kiwi/issues/771
For what it's worth, livecd-tools / appliance-tools use DNF's API, while kiwi uses DNF's CLI. It's important that this is configurable through both means.
I think it is a duplicate of https://bugzilla.redhat.com/show_bug.cgi?id=1673333 +1 for this feature, I wanted to strip locales installed into rootfs when building locales
