fc1 --> rawhide problems

[Marcello Mezzanotti <mezzanet iname com>]

hello all, i have a fresh install of fc1, i want to upgrade to rawhide
via yum, so i modified yum.conf to only use rawhide repository, after a
yum update/upgrade, all i got is an error about loop excedded
now is something about initscripts and mkinitrd that needs mount but
mount isn't disponible!!!

any help?
thanks
