Hi James, Specific ordering is sorely missing in the daemontools inspired tools. This has nothing to do with sv check: They're two different things. Ordering is what you have in a non-parallel startup: Do them in a specific order. It's what you accomplish with the numbering for SysVinit in the /etc/rc.d/rc3.d symlinks. sv check and checking in general is about process dependencies, not order. One does not eliminate the need for the other. If the network doesn't come up during its turn, you don't want to start sshd later, even though your *attempt* at the network came several seconds before your attempt at sshd. Where ordering aids dependencies is that it makes it likely that your services will fire right up, instead of repeatedly (and indeterminately) failing for lack of a dependency.
