Could you tell me what read-only mean? For your files, you are the owner, and you can give yourself read-only or read-and-write permission. Check for commonalities in the file locations. I have been using it from the beginning including the days where we had to install it manually and over the years it has matured a lot too. This provides a simple system of dependencies between hooks and scripts. Many such scripts also provide hooks for other shell scripts to be executed at certain points during the boot process.
Unfortunately, it is usually not as simple as using a conventional filesystem mounted with the read-only option. After I try to mount sda1, I'm going to want to know about something I think I read.
