I apologize for the slightly late reply.  I've been trying to get caught
up on email.

I do like this idea with two provisos:

1) That a recommendation be put in about each init script needs to
include an OPTIONS or PROGOPTS or similar variable on its command-line.
This allows customization through addition of command-line arguments.

2) That initscripts be discouraged from putting command-line arguments
directly in the scripts.  Instead they should be placed in the variable
from part 1) in /etc/sysconfig/progname.  Putting command-line arguments
directly into the init script means that I can't remove those arguments
without modifying the init script.  There could be some exceptions to
this guideline.  An example would be something to set the uid of the
program in question, such as adding "-u named" in the script to start
named.

To my current memory, these two situations cover every time that I have
needed to modify an init script.  (There might be others I can't think
of, though.)
