[PATCH 1/1] defaultenv-2: add boot sequence

[Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>]

Boot will boot run sequentially the script in /env/boot.d

if not global.boot.default or global.boot.default == seq
or -s is sepecified
start the boot sequence

we do not boot the boot sequence by default t keep retro compatibility
