New Revision: 298243
URL: https://svnweb.freebsd.org/changeset/base/298243

Log:
  Add a new installation type to bsdinstall/zfsboot: BIOS+UEFI
  
  Installs both pmbr+gptzfsboot as well as boot1.efifat in separate partitions
  The resulting system can be booted with either UEFI or BIOS/CSM.
  Preference is controlled by the user's firmware boot settings.
  
  This is now the default for zfsboot installs
