The \OHPCVerTree{}.3 release includes a major update (v3.8pre) of the \Warewulf{}
provisioning system. This update brings many improvements such as iPXE support
and \texttt{parted} filesystem partitioning, but upgrading requires some
additional steps. In particular, any existing bootstrap images should be
exported and re-imported to insure new initramfs capabilities are enabled.
