My laptop didn't like your cd's, so I copied everything to harddisk, made the boot disk from the italian directory (confirmed now it was really the italian one) to test some translation issues and... all messages (repeat, all) are in English. In case it matters, I was upgrading from 6.2
This defect is considered MUST-FIX for Winston Gold-release
Please verify brock.
verified ... this occurs only for a hard drive install (ie boot.img w/CDROM, bootnet.img properly use italian language in the anaconda second stage install while boot.img w/hard drive install uses english in second stage) ... thanks for your report!
JFYI, still there in RC1. Maybe you had already cut the isos?
Still there in RC2 hd upgrade/install.
The final release has shipped so this cannot be corrected now.
