With class_simple support, the initscripts now look as follows.
Confirmed this works on a RHEL4-U1 beta kernel build, sysfs makes
/dev/ipmi0 for us. Per Corey, there's no real tool that uses the
/dev/ipmi symlink, they should be using /dev/ipmi0. So I removed the
creation of that symlink in the patch below.
The initscripts are necessary until there's a mechanism that can
autodetect the presence of IPMI-capable hardware and load the modules
automatically. That's a future task, and not one I want to hold this
up for. This will work for now.
Thanks,
Matt
