It's intentional (although not very aesthetic). The cryptsetup initramfs
scripts allows all other disk-related scripts to run first since you could
have an encrypted LVM volume as well as LVM on an encrypted volume.

After setting up the encrypted volume, the cryptsetup initramfs scripts
will then perform the LVM/EVMS/etc setup when necessary.

So the process is more like this:

  1) LVM/EVMS/md/etc
  2) cryptsetup
  3) LVM/EVMS/md/etc
