Good to know, thanks, but does chflags nodump allow one to block off a dump of an entire directory and all its subdirectories? That would mean that dump would need to build an internal directory tree, which is quite counter to the (classical) design of dump. I can see that chflags can easily block the dumping of a particular file (inode), but that's pretty limited in usefulness (maybe good for bad block inodes though...)
