Programs0 is back with all its data intact. Any chance that could be added to the script that installs Preinit in the first place?

I could, but proper results rely on doing a lot more than just creating that directory, and the way I check to see which directory to use (/etc/preinit.d vs. /programs0/preinit.d) ... wait.

Yes. I can do that. If you don't see it later today, remind me.
