Most systems need an early bootstrap phase for one-shot tasks and necessary one-time probing. This phase usually runs well before any networking is setup. This commit adds support for that 'S' runlevel, and also extends the number of possible total runlevels to nine. For the one-shot tasks that run in bootstrap two new finit.conf cmds have been added: - task: For one-shot tasks that can be started in parallell - run: For one-shot tasks that must run in sequence Signed-off-by: Joachim Nilsson <troglobit@gmail.com>
