The "init" and "reboot" (actually halt) follow a circuitous route
to the shutdown program. They depend on a variety of files or
environment variables and work well in a fully configured workstation
environment. They probably won't work correctly in a stripped down
file system of an embedded system.
Also, the code in the kernel may have to be adapted based upon the
boot rom used. Jumping into rom is a questionable operation. I am
adding the checkstop/reset patch that was posted a while back to the
2.4 tree (and probably backported to 2.2 as well) as a configuration
option. This isn't a complete solution either, as it prevents passing
parameters around that are sometimes useful.
Options galore....choose what works for you....not a single solution
for everyone....
