1. Please add percent unit (%) for create a new partition.
    sgdisk -n 1:0:50% -n 2:0:0
    Very often we want to split the disk in half.
    Now you have to recalculate it manually.

  2. Support in gdisk for generating UUID for /var partition using systemd
    machineid UUID.
    If we change the type to a Linux /var partition, it should at least
    display the UUID that should be set on this machine to be valid for the
    current machineid.
    Support in sgdisk would also be usefulL: sgdisk -t 4:8310 -u 4:auto
    (auto works only if type is 8310).
