ZFS is a modern filesystem originally developed for SOLARIS. It provides many functionalities such as snapshots, data compression, data recovery and many more. For more information about ZFS on linux, visit http://zfsonlinux.org You'll need the kernel source code to be able to compile this. This package is kernel dependent, so you'll need to recompile it for every new kernel you choose to run. If you don't have a /usr/src/linux symlink pointing to your real kernel directory (the script looks for it there by default), specify your kernel source destination by LINUXPATH=<path to your kernel source> ./zfs-on-linux.SlackBuild NOTE: you better run this on x86_64 systems.
