In most/all cases for images, just a truncate is needed as Glen
mentioned.  The growfs(7) rc script is run at first boot to size
up the root fs as needed.  It can always be run manually later via:
service growfs onestart

if/when the size of the disk changes...

Hmm, just noticed that growfs(7) isn't linked from growfs(8), guess
I need to fix that.
