Thank you. That's exacly what I wanted to know. Even thou it is not very
happy, as this problem also means that duplicating fedora install on
different hardware can result in unbootable system, because initrd
contains only IDE driver it was installed on. For me as I am from time to
time cloning installs its not very good approach.
Simply remaking the initrd after you clone should solve this - mkinitrd
has the logic to autoprobe the root filesystem, and should catch any
changes even if you don't edit modprobe.conf.
