 Finally, we create the root filesystem array. mdadm gives a warning here about using a recent metadata device as a boot partition. Since this isn't our boot partition, we can ignore this warning and go ahead with creating the array.

 We now create the RAID devices with a single disk only. This is unorthodox but required while our other disk is in use to stage the install. The first drive is creating using older metadata, as noted in the documentation.

-One of the reasons for moving on from Gentoo was a lack of any definitive process in the community forums or documentation for setting up a RAID based system. When googling this, all of the related documentation seemed to generate hits from the Arch community docs.
+It should be noted that this guide focuses on setting up the system using a single drive, then adding the second after the install is complete, in order to have both systems running at the same time and perform a migration.
