'all' partition size is limited to 2TB

[bastelfreak]

following config:

DRIVE1 /dev/sda
HOSTNAME example.con
BOOTLOADER grub
PART / ext4 500G
PART swap swap 2G
PART /var ext4 all
IMAGE /root/.installimage/../images/Debian-84-jessie-64-minimal.tar.gz

Results in the following partition table:

# fdisk -l

Disk /dev/sda: 5.5 TiB, 6001118633984 bytes, 11720934832 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: gpt

Partition table entries are not in disk order.

sda3 isn't using the whole disk. The beginning of the debuglog:

Problem is in functions.sh at line 4023.

  # if we have no more than 3 partitions
  else
    PART_ALL_SIZE=$(echo "$DRIVE_SIZE - $PART_WO_ALL_SIZE" | bc)
    if [ "$PART_ALL_SIZE" -gt "$LIMIT" ]; then
      PART_ALL_SIZE="$LIMIT"
      [ -z $result ] && result="PART_CHANGED_ALL"
    fi
  fi

Add some check if the all partition is not / and the parttype is GPT and skip the clamping to the limit then?
