Detailed Description

Currently there are multiple sources to manage what font packages should be installed for a Fedora release and spins, such as comps, langpacks, lorax, workstation-ostree-config, and fedora-kickstarts. This sometimes makes compilcated to update the default fonts. So we want to introduce new meta packages into langpacks and replace a list of font packages with it. We expect to improve such situations by updating langpacks only then.

• langpacks-font-core-sans, langpacks-fonts-core-serif, langpacks-fonts-core-monospace, langpacks-fonts-core-emoji
  • Metapackages to pull the default font for Latin characters and emoji
• langpacks-font-default-cjk-sans, langpacks-fonts-default-cjk-serif, langpacks-fonts-default-cjk-monospace
  • Metapackages to pull the default font for CJK
• langpacks-font-default-sans, langpacks-fonts-default-serif, langpacks-fonts-default-monospace
  • Metapackages to pull the default fonts for other languages
• langpacks-font-extra-<language code>
  • Metapackages to pull extra fonts for certain languages if any

Benefit to Fedora

This Change provides the easier way to manage, and install our default fonts on Fedora. In current package sets, langpacks offers non-fonts packages to be installed even though one don't want to install them. After this Change, one don't need to install those extra dependencies for the purpose of the font installation.
