Description of problem: In F37 we moved the gettext runtime programs to gettext-runtime. So assuming blivet-gui-runtime does not require any translation management tools (like msgcat or xgettext) at runtime, it should be possible for it to only Requires: gettext-time (instead of gettext). Additional info: We can open a PR for this if it helps.
I forgot to add: the goal here is only to install gettext-runtime in the Fedora live image(s), etc.
