Random question:

Way back when I used union mount code (under OS/2) that would mount the first
filesystem read-only, and allow you to cache changes to it in a second
filesystem. (So you could do a build of slightly self-modifying code, a lot
like the Linux build in 2.4 was, against a read-only tree.)

Would this be a good tool for that sort of application? (There's all sorts of
other "trial run" type applications; running stuff against database snapshots
and then seeing what the deltas are, etc...)
