Yes. I am also currently working on integrating s6-linux-init into
Adélie in order to have s6-svscan as pid 1, this should be ready
some time this week. Users will have a choice between standard
sysvinit with a supervised s6 tree (as it is now) and s6-svscan as
pid 1.

  Yes, but that is undocumented and shouldn't be relied upon - and
there's no readiness notification for "respawn" lines anyway, so
relying on order could be racy. For all intents and purposes, all
inittab lines after "sysinit" are spawned in parallel or without a
specified order.
