Hi, I'm working on a quite big project, namely LLVM. As you can imagine, launching a `make install` it's quite time consuming, in particular in Debug builds. However I'm using a smart file system (BTRFS on Linux) which supports "reflinks", which basically means that it's possible to create copy-on-write duplicate of a file, without having to write the file contents again. This can be easily done using `cp` (from the GNU Coreutils) with the --reflink parameter.
I wrote a very dirty patch launching cp with a system call, but if you're interested I can put up something better. Currently reflinks are supported only by BTRFS on Linux, but I think it will be available also for ZFS users soon. I'm aware this is useful in a very specific setting but the benefits are so evident that I think it's worth implementing it. -- Ale -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.
