init script order: How to determine order WITHOUT rebooting?

overkll

Anyone know how to list/determine the order of execution of the initscripts without rebooting?

rc-update can show what will be started, but not the order. Kind of a pain in the ass to try and figure it out by looking at the "depends" function in every init script. I know about the /etc/init.d/<service> (ineed|iuse|needsme|usesme) capability, but again, one needs to look at every script and try to order it up manually.

There should be something simple like "rc-update show order" or "/sbin/rc --pretend". Anyone out there with the answer? Inquiring minds want to know.

Well, since I didn't think this feature existed, I filed a bug report. Looks like the feature will be added to baselayout-2.0.0_rc6.

Actually, I did answer, but I quickly deleted my post when I discovered it wasn't 100% accurate.

I recommended this:

When I was digging around for an answer, I came across /var/lib/init.d/deptree. AFAIK, this is where the order is stored. I didn't feel like trying to decifer it at the time.

Yes, that is the dependency tree. It's essentially the depends information from the init scripts (need, before, after, etc.) recast as a collection of bash arrays. The trace_dependencies function from /lib/rcscripts/sh/rc-services.sh uses that structure to determine the ordered dependencies of any given script. The section of /sbin/rc that starts services is little different from what I posted above, yet the order comes out different...puzzling.

You need to fake a function like so after sourcing rc-services.sh

is_runlevel_start() { return 0; }

trace_dependencies works differently if a runlevel is starting or stopping.
