Only the traditional SysV. Debian since squeeze uses startpar so will start *some* things concurrently (same Sxx number). And where that happens, it's much simpler to see/control it as files in /etc/rc2.d, than e.g. events being triggered and such. > Well, the scripts may be started sequentially, but this doesn't mean > that the daemons will be and always in the same order. Actually, even if they forked in the same order every time, they might not be *ready* in the same order. That would be the rationale for readiness protocols and other features of the more complex init systems. > In (1): > spamd start > wicd start/OK > sshd start/OK > spamd OK > postfix start/OK > > In (2): > spamd start > sshd start/OK > wicd start/OK > spamd OK > postfix start/OK > > This isn't deterministic at all. I think that's just because insserv+startpar was being used here, not the traditional SysV.
