= Generating Bootcharts for a UME Image =

== Creating an Image with Bootchart Enabled ==
 * Launch image-creator
 * Open target chroot
 * In target chroot:
  * `sudo apt-get update`
  * `sudo apt-get install bootchart`
 * Create an image and write it to a USB key
 * Install the image on the USB key (or run a live image off the USB key)
 * When the system has finished installing and booting, a png containing a boot chart will be generated in /var/log/bootchart
 * To generate a new bootchart, simply reboot.  For example, in terminal:
  * `sudo shutdown -r now`
  * A new png will automatically be created in /var/log/bootchart
 * Note: performing a `sudo apt-get install` on the running image itself will not work 

== Creating an Image that Does Not Use SquashFs ==
The following steps describe how to create an image that uses ext3 for the rootfs rather than squashfs:
 * Close image-creator
 * Add the following line to the [installimage.menlow-lpia-ubuntu-hardy-ppa] section of ~/.image-creator/image-creator.cfg:
  * `use_squashfs=0`
 * Launch image-creator
 * Create an Install USB image.  A Live image cannot be used as a Live image always uses squashfs.
 * Write the created image to a USB key
 *To verify that squashfs has been effectively disabled, make sure that the install.cfg file at the root of the usb key has the line:
  * `use_squashfs=0`
 * NOTE: An image that does not use squashfs will use significantly more space in the device's rw storage partition.  Be sure that the device that you are installing the image on has a large enough rw storage paritition to accomodate the uncompressed filesystem.  This usually means a rw storage partition that is > 1.3 GB.
 * NOTE: Installation will take longer than usual as files need to be individually decompressed and copied to disk

== Misc Notes ==
 * Current bootchart version for hardy as of 3/20: 0.9-0ubuntu7
