from within the chroot. It also fixes a number of style issues. It changes the meaning of cros_workon "list-all" to list all available packages, and adds "list-live" to list all live packages. It changes things that load chromeos-common.sh from the installer to load it from /usr/lib/installer. BUG=chromium-os:4230 TEST=synced, rebuilt chroot, made packages, made images, built chrome from source, and wrote an image to a USB stick.
