initrds are created automatically for you upon kernel package
installation in most linux distributions (fedora included). this means
that the mkinitrd/mkinitramfs-script will sniff around your system and
decide which modules (dm, ext3, hba-drivers, etc) to include in the
initrd and also sometimes decide which scripts to call (vgscan and
friends) and whether to include lvm-related tools into the initrd.
Similar story for software raid.

This means that if you take the initrd and try to boot a system that
doesn't have LVM you're doing something wrong. initrds are not supposed
to be portable, however this will of course depend very much on the
distribution.

Hope this answers your question.
