        One possibility is to use a "union" file system, overlying a RW FS
over the RO / and /usr. That way it should be fairly simple to modify files
transparently as well as to later seeing which files have been modified.

        Union filesystems appeared with BSD4.4 and won't probably be
available on most UNIXes. But they're a neat idea, and if you ask for it,
who knows, maybe your vendor will provide it in the next release?

        Just a few ramblings.
