Here's an example in FC2 where I could have used modularization of "all the
normal stuff", in order to implement EVMS.   Here EVMS is not managing the
boot drive, so it's not in the initrd.  But it should be initialized in
rc.sysinit so that its volumes can be mounted simply by having them
in /etc/fstab like so:

  /dev/evms/raid1         /export/raid1           xfs     defaults,quota,grpquota 0 2
