the fundamental problem here is that Fedora uses LVM as its default
partition type, and this is not supported by a variety of older/other
you can mount the LVM disk, but not by just using mount(1). i've had
to do this a few times, and it is *MINDBLOWINGLY* difficult. i don't
even recall the command set i had to use. i think it was the md* tools
the upside of using LVM is that you can endlessly reconfigure the
partition(s) (bigger or smaller), including adding/removing other
drives with almost no effort whatsoever. the downside is that if you
just want the disk to be /dev/sdb<foo> ... its not so easy.
i believe that fedora and/or redhat went through quite a long debate
about this, and ultimately decided that the overall benefits of LVM
vs. just ext(3|4) outweighed the drawbacks. obviously, this doesn't
mean that its true in every case. i'd also guess that its true for
most RedHat users and not true for most Fedora users.
