Proposing as Beta blocker, preupgrade is required to work at Beta.

I think this could be caused by the same option as in bug 806966

Does preupgrade use inst.repo=hd: option??
Comment 3 Adam Williamson 2012-03-26 13:36:00 EDT
Discussed at 2012-03-26 QA meeting acting as a blocker review meeting. Accepted as a blocker per criterion "The installer must be able to successfully complete an upgrade installation from a clean, fully updated default installation (from any official install medium) of the previous stable Fedora release, either via preupgrade or by booting to the installer manually. The upgraded system must meet all release criteria".

Yes, IIRC.
Comment 5 Adam Williamson 2012-03-26 17:32:33 EDT
Here's the preupgrade grub2.cfg entry:

linux /upgrade/vmlinuz preupgrade repo=hd::/var/cache/yum/preupgrade ks=hd:UUID=blahblah:/upgrade/ks.cfg stage2=hd:UUID=blahblah:/upgrade/squashfs.img

so yeah, it uses repo=hd: . I guess we should make this a dupe of 806966.
