Bcachefs is a copy-on-write (COW) file system for Linux-based operating systems. [3] Features include caching, [4] full file-system encryption using the ChaCha20 and Poly1305 algorithms, [5] native compression [4] via LZ4, gzip [6] and Zstandard, [7] snapshots, [4] CRC-32C and 64-bit checksumming. [3] It can span block devices, including in ...
Environment Modules on Scientific Linux, CentOS, and Red Hat Enterprise Linux distributions in the environment-modules package include modules.csh and modules.sh scripts for the /etc/profile.d directory that make modules initialization part of the default shell initialization. One of the advantages of Environment Modules is a single modulefile ...
ext4 (fourth extended filesystem) is a journaling file system for Linux, developed as the successor to ext3.. ext4 was initially a series of backward-compatible extensions to ext3, many of them originally developed by Cluster File Systems for the Lustre file system between 2003 and 2006, meant to extend storage limits and add other performance improvements.

make menuconfig is one of five similar tools that can assist a user in configuring the Linux kernel before building, a necessary step needed to compile the source code. make menuconfig, with a menu-driven user interface, allows the user to choose which features and modules to compile.
inotify (inode notify) is a Linux kernel subsystem created by John McCutchan, which monitors changes to the filesystem, and reports those changes to applications.It can be used to automatically update directory views, reload configuration files, log changes, backup, synchronize, and upload.
udev (userspace /dev) is a device manager for the Linux kernel.As the successor of devfsd and hotplug, udev primarily manages device nodes in the /dev directory. At the same time, udev also handles all user space events raised when hardware devices are added into the system or removed from it, including firmware loading as required by certain devices.
Unlike existing Linux boot images, the Dracut framework attempts to introduce as little hard-coded logic into the initramfs as possible. [1] The initramfs has essentially one purpose: locating and mounting the real root file system so that the boot process can transition to it. [ 1 ]
For distributions based on .deb and .rpm files as well as Slackware Linux, there is CheckInstall, and for recipe-based systems such as Gentoo Linux and hybrid systems such as Arch Linux, it is possible to write a recipe first, which then ensures that the package fits into the local package database.
