There are no utilities included for automatic file system re-sizing. However, it’s not hard to do manually. Once booted:
sudo fdisk /dev/mmcblk0
a. Delete the second partition (d, 2),
b. then re-create it using the defaults (n, p, 2, enter, enter),
c. then write and exit (w). Reboot the system, then:
sudo resize2fs /dev/mmcblk0p2
d. restart (eg from terminal – ignoring any running process)
