Description of problem:
NetBSD uses a script called "rcorder" to dynamically order the rc*.d
startup scripts. Scripts specify RPM-like dependencies (REQUIRES:,
PROVIDES:), and rcorder automatically orders the scripts such that all the
dependencies are satisfied.
When shutting down, you just reverse the list.
This is far more elegant than manually ordering things based on filenames
(S00, S11, S14, ...).
Obviously, there are several tools that would need to be dropped or
modified to work with the new scheme (/etc/rc, chkconfig, GUI config
tools), but I think the elegance and flexability would be a big win.
If you don't feel like grabbing NetBSD to look at this, I've ported it to
linux. You can find my port at:
The archive includes a spec file.
Steps to Reproduce:
Grab the tar archive, build, run...

linux port of rcorder
FreeBSD recently adopted this as well. The nice thing about dependency-ordered
startup is that you can do a number of things in parallel and get your system up
I'm thinking about getting the linux port up and running locally - it would be
awesome if RedHat could adopt this system.
In some informal testing here, the startup time was so overwhelmingly dependent
on disk access that parallelization didn't really help much.
Closing out bugs on older, no longer supported releases.
It's highly unlikely that a straight switch to rcorder will ever be done.
