Your characterization of CVSup isn't accurate. CVSup is a fully general mirroring tool which includes additional features and speed-ups that are oriented toward CVS repositories. CVSup can be used to mirror anything, including binary files, hard links, symbolic links, and device nodes. It selects from a number of different kinds of optimizations, depending on the type of file it is updating. In addition to RCS file optimizations, it also includes the rsync algorithm, a specialized algorithm for log files, and some others. At least one commercial company employs CVSup to do field upgrades of their FreeBSD-based product. In that application, CVSup upgrades the entire root and /usr filesystems.
