[arch-projects] [initscripts][RFC] deprecating ck_depends

Hi guys,

I'm trying to resolve FS#20903, and I think the only sensible solution is to 
stop using the ck_depends function. I'd like to hear your opinion on this.

This is the situation:
ck_depends was introduced in 
as a simple mechanism to implement dependencies.

What it does, is that it allows an rc script to start other rc scripts. 
However, it is not equivalent to adding the depedent rc scripts to the DAEMONS 
array. The problem is that at shutdown, we have no record of when the 
dependencies were started, and therefore treat them as if they were started by 
the user during runtime.

The end result is that the dependencies of a daemon are started before the 
daemon (as expected), but also stopped before the daemon (contrary to the 

I don't think parsing the rc scripts at shutdown to figure out the dependencies 
could work, nor do I think it is in the spirit of our initscripts. The only 
correct solution (IMHO) to resolve a dependency is to ask the user to add the 
relevant daemon to the DAEMONS array.

I therefore suggest marking ck_depends as deprecated, and print a warning 
whenever it is used.

Did I miss something? Any opinions?
