Modify Partition
I usually expand the partition to 4GB form the default 2GB so I can re-image my installs. Once I've finished building my image I then expand the partition to maximum using the raspi-cofig utility.
- Delete partition 2. Making notice of where it starts.
- Create a new primary partition with the same starting block and finish at block 8388608
fdisk /dev/mmcblk0

resize2fs /dev/mmcblk0p2
