Hi there, I am wondering whether it is possible to have a read-only fs (CDROM, image, etc) as part of an LVM-managed volume. I see references to COW (copy-on-write, I'm hoping :)) in the kernel drivers/md/ files, but it's not at all clear to me whether or not the current drivers can be used to implement a "translucent" or "inheriting" file system (one where a base fs is given, on r-o media, and changes to it get recorded on another device, presumabely a r-w fs). Please let me know whether this is currently possible, being planned for the future, or if I'm making no sense above & you want me to clarify :). For a not-quite-mature example of what I'm talking about, see translucency.sf.net.
