Hmm...I hadn't considered that. You're correct of course. I've just tested /etc/test.sh :

!#/bin/sh
while true
do
echo "1\n"
done

remounting ro, rw,ro etc worked fine without any hiccups. So another potential strategy: JEmplode puts apps into /programs0/install/ , and N00install moves any /programs0/install/ entries into /programs0. There isn't any need to remove N00install - it should just exit gracefully when it has nothing (left) to do. The only issue with this approach is that it makes it more difficult to utilise /programs1 on dual-drived empegs, but that really isn't a concern at the moment - since the preinit script needs to know the location anyway.(unless we start setting PATHs etc). My goal here is to make 3rd party application installs as painless as possible for the non- unix/linux -savvy, and to perhaps make it quicker and easier for the rest of us...
