    Linux distributions that have highly modified kernels — for example, real-time computing kernels — should be listed separately. There are also a wide variety of minor BSD operating systems, many of which can be found at comparison of BSD operating systems .

  7. Device mapper - Wikipedia

    en.wikipedia.org/wiki/Device_mapper

    The device mapper is a framework provided by the Linux kernel for mapping physical block devices onto higher-level virtual block devices. It forms the foundation of the logical volume manager (LVM), software RAIDs and dm-crypt disk encryption, and offers additional features such as file system snapshots .

  8. pstree - Wikipedia

    pstree is a Linux command that shows the running processes as a tree [1] [2] [3]. It is used as a more visual alternative to the ps command. The root of the tree is either init or the process with the given pid. It can also be installed in other Unix systems. In BSD systems, a similar output is created using ps -d, in Linux ps axjf [4] produces ...
