Hi, again some results from the unionfs theory. Seems the real problem is not the unionfs, which seems to work, but instead the problem to actually mount an existing file system as read-only. For Mac OSX seems to work only the was to eiter direct mount from CD, or to mount a disk image (.dmg).
The missing link seems to be a "Null file system" (nullfs), which allows to mount a folder into another folder. Nullfs seem to exist on other systems, like FreeBSD, but not on Darwin (or at least it is not build and deployed). There seem to be some ideas in regards to being able to use a nullfs as a Darwin kernel extension (.kext), but these ideas don't seem to be finished / buggy. Sorry, doesn't seem to work that way.
