A sysadmin never has the edit any of those files. If they need to do
something special they can always change the kernel to patch the init
system to change what the script can do in arbitrary ways. </sarcasm>
While such scripts should allow all reasonable and forseeable
configuration settings be applyable outside, there are still all the
"unreasonable" and unforseeable changes that happen every day.
(execute some additional clean-up or preparational command just before,
run something two times or differently, ...).
If a admin is not able to do those, it's a crap system. So at least
every script should be overrideable by some script the admin supplies.
So what is the advantage of not having those files in /etc? (In
/etc/ they should be config files (ideally conffiles). If they are not
conffiles, they do not belong in /etc).
The advantage of having them in /etc are:
- every user understands how to change them (no need to find out where
to copy a script so it overrides the distribution suplied one).
- if there are changes the usual conffile handling make sure one notes
if the original file changes
