Setting Up Library Paths via Script

With the whole package contents in place, you need to make sure that Chromium will be able to find its libraries and other needed files. There is a pre-fabricated script for this.

1. Log into Local Terminal as root.
   

2. Change into the /custom/chromium-browser directory.
   

3. Enter the command ls -l.
   

4. You will see that instead of a single script as in the previous example there are the etc/ and usr/ directories. They include many libraries and other files that Chromium will need to run.
   However, it expects these directories not within the /custom/chromium-browser/ directory, but in the filesystem root, where system directories such as /usr are located. The Initialization Script for the Custom Partition will fix this by setting up symbolic links, so that for example /custom/chromium-browser/usr/lib/library.so will appear to be in /usr/lib/library.so, where Chromium expects it.
   

5. Use the GNU nano editor to create the file custompart-chromium-browser and put the following contents into it - alternatively, edit the file elsewhere and copy it into /custom/chromium-browser/:

   #!/bin/sh
   ACTION="custompart-chromium-browser_${1}"
   # mount point path
   MP=$(get custom_partition.mountpoint)
   # custom partition path
   CP="${MP}/chromium-browser"
   # output to systemlog with ID amd tag
   LOGGER="logger -it ${ACTION}"
   echo "Starting" | $LOGGER
   case "$1" in
   init)
   	# Initial permissions
   	chown -R root:root "${CP}" | $LOGGER
   	chmod 755 "${MP}" | $LOGGER
   	# Linking files and folders on proper path
   	find "${CP}" | while read LINE
   	do
   		DEST=$(echo -n "${LINE}" | sed -e "s|${CP}||g")
   		if [ ! -z "${DEST}" -a ! -e "${DEST}" ]; then
   			# Remove the last slash, if it is a dir
   			[ -d $LINE ] && DEST=$(echo "${DEST}" | sed -e "s/\/$//g") | $LOGGER
   			if [ ! -z "${DEST}" ]; then
   				ln -sv "${LINE}" "${DEST}" | $LOGGER
   			fi
   		fi
   	done
   	ldconfig
   ;;
   stop)
   	killall -q -SIGTERM chromium-browser
   	sleep 1
   	killall -q -SIGKILL chromium-browser
   ;;
   esac
   echo "Finished" | $LOGGER
   exit 0
   

   Use this as a script template for your Custom Partitions, replacing all instances of chromium-browser with the directory name of your CP.

   
   

6. Make the script executable with the following command:
   chmod a+x custompart-chromium-browser
   

7. Run the script:
   ./custompart-chromium-browser init
   It should run and finish without any errors.
   The library paths are set up now.
