Comps has language support groups that define specific packages that should come in when a particular language is picked. This is not functioning currently in the re-written yum backend of F18's anaconda. Because of this some fonts will be missing, same with tools like m17n, and scim-tables, etc...
Proposing nice to have, as it would be nice for people using those languages get the bits they need.
What would the fix for this look like? How icky is it?
The fix just got proposed upstream, basically takes the lang values we're seeing now "es_ES.UTF-8" and truncating it down to just "es". The rest is existing code.
Patch posted.
Discussed 2012-11-07 NTH review meeting: http://meetbot.fedoraproject.org/fedora-qa/2012-11-07/f18beta-blocker-review-7.2012-11-07-17.03.log.txt . Accepted as NTH as it's a significant issue for non-English users that cannot be fixed with an update.
anaconda-18.27-1.fc18 has been submitted as an update for Fedora 18. https://admin.fedoraproject.org/updates/anaconda-18.27-1.fc18
18.27 has since gone stable, so let's close this. I'm assuming it actually works.
