fc7t4: still eating babies?

However, I found some bugs. In particular: 1) two drives in systems, installing onto one, not doing anything to the second, but try to mount the second on say /mnt/drive/montsouris so that one can read files from it. Kills anaconda dead. 2) same as one, but without the mount. Reboot: it looks like grub written to the wrong drive (ie, installing on to drive one, grub info written to drive two). UGH!!!! Minor panic as I contemplate a day of moaning and non-paris rando velo riding, but then I reboot into the fc7t4 disk and mount drive two manuall: data still intact, apparently boot info fried. Ie, there is a directory "/boot" but nothing is in it. Any pointers on how to get drive two bootable again? Drive two is an up-to-date FC6 install, or used to be. Thanks, benjamin ps. Usually I physically unplug the second drive to avoid this kind of thing. Ever the optimist.... pps. please cc my gmail account on replies as my mail is now screwed.
