Well yes, they might be overwritten. Hopefully, apt-get will warn
you before doing so. I don't believe I've modified init scripts
on my Ubuntu/Debian systems, so I don't know whether "apt-get
upgrade" or something similar will over-write them. But, on my
Gentoo system, I have. And, they will possibly be replaced,
although Gentoo's package manager (Portage) warned me before doing
so. In my case, I was able to move my new stuff to a separate
script and then add that new script to the boot process.
I don't know your needs, but if possible, you're best off if you
create a new script of your own, rather than modifying an existing
script, and add your new script to the appropriate run levels.
Debian makes that easy to do. You probably already found the
following link from the above link, but just in case ...
http://www.debian.org/doc/debian-policy/ch-opersys#s-sysvinit
This link shows how to use update-rc.d to add your new script to
the default run levels.
