E. Managing System Images
System images provide 1:1 copy of the Debian OS installed on a CF/microSD card. The image has
the size of a medium being used to produce the system image. For KS8695 based devices it is ca.
2GB and for OMAP3 based devices ca. 4GB. In the case of OMAP3 based devices a special utility
raspi-config
70
is provided to automatically enlarge partition/file system to the real physical size
of a medium, i.e. if you burn the image to a 8GB card, it will occupy only 50% of the medium,
after executing raspi-config whole 8GB will be at your disposal. To expand the root partition
start raspi-config and select “expand_rootfs” in the menu as show in Figure 36 and exit. The root
partition expanding runs in two stages: at first the partition will be enlarged and after a reboot
the file system will be enlarged too.
