#You can also manually partition your usb flash drive on your computer

[[ -f /tmp/usb_format.progress ]] && {
  exit 0

touch /tmp/usb_format.progress

umount /sd
swapoff /dev/sdb2

sleep 2
cat /pineapple/modules/Advanced/formatSD/fdisk_options | fdisk /dev/sdb
sleep 2

umount /sd
mkfs.ext4 /dev/sdb1
sleep 2

mkfs.ext4 /dev/sdb2
mkswap /dev/sdb2

mount /dev/sdb1 /sd
swapon /dev/sdb2

rm /tmp/usb_format.progress

fstab

    option anon_mount '0'
    option auto_swap '1'

config mount
    option target '/sd'
    option device '/dev/sdb1'

    option options 'rw,sync'

option device '/dev/sdb1'

This will most likely fail if another pineapple will not use sdb as device. Use: /dev/sdcard/sd1 and sd2 for swap.
