[snip] # This script extracts the contents of ITU media and install them onto the # miniroot. It also stores them in the directory /tmp/ITUs. At the end of # install, it is invoked (with rootdir arg) to install the contents of # /tmp/ITUs onto the target OS. [/snip] This message posted from opensolaris.org
