However I need to do the "--init" to ensure all the modules are correctly checked out. When manually deleting one of the packs in my testing git did the right thing and fetched the missing pack data. Once the submodules move forward I'll double check the incremental update works as well. > > > Alex > >> - sudo apt-get update -qq >> - sudo apt-get install -qq ${CORE_PKGS} ${NET_PKGS} ${GUI_PKGS} ${EXTRA_PKGS} >>

A significant portion of the build time is spent initialising all the sub-modules we use in the source tree. Often this is almost as long as the build itself. By pre-seeding the .git/modules tree this will hopefully improve things. Signed-off-by: Alex Bennée <alex.bennee@linaro.org>
