Not true.

In fact, it's very supported to drop in scripts into
/etc/init.d/, and countless other directories under /etc --
such as the system crontabs, etc...  The whole reason for the
"directory" design is to make it easy for the packaging
system to be add/remove scripts for different pieces of
software, instead of modifying pre-existing files.

E.g., a great example of that comes up here regularly is the
/etc/yum.repos.d, instead of modifying the stock yum
configuration/repo files.

Again, in dealing with Red Hat support myself, I have to
disagree.

Considering the recommended approach for any 3rd party
software package is to leverage such directories where files
can be added, instead of modifying existing files, the a site
admin who does that "proper" is not doing anything "wrong."

Well, I think we've gotten well away from the recommendation
that you try to use "service iptables save" to now debating
/etc/init.d/(customscript) v. /etc/rc.d/rc.local.

P.S.  Non-Red Hat note -- also remember that
/etc/rc.d/rc.local is _not_ LSB last time I checked.  Several
distros (and even non-Linux releases, such as Solaris) define
a /etc/rc#.d/S99local instead, and I think that's what Red
Hat now does too (starting with what distro release?), which
then points at the "local" for their implementation
(/etc/rc.d/rc.local, being the legacy for Red Hat).  So one
might argue that "/etc/rc#.d/S99local" is the script.  But
now I'm just being anal.  @-ppp
