Trying to install F11 beta on my laptop fails with "File System error detected, cannot continue"
It seems to barf on /dev/sda2 which is an opensolaris ZFS partition
/dev/sda2   *        7753       10302    20482875   bf  Solaris

It might be related that I have opensolaris' grub installed (as it's the only one that can read/boot zfs). Anyway, relevant logs below
