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.
the middle three characters, r-x, define permissions for the Group class (i.e. the group owning the file) the rightmost three characters, ---, define permissions for the Others class. In this example, users who are not the owner of the file and who are not members of the Group (and, thus, are in the Others class) have no permission to access ...
Curses is designed to facilitate GUI-like functionality on a text-only device, such as a PC running in console mode, a hardware ANSI terminal, a Telnet or SSH client, or similar. Curses-based software is software whose user interface is implemented through the curses library, or a compatible library (such as ncurses ).
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.
The inode (index node) is a data structure in a Unix-style file system that describes a file-system object such as a file or a directory. Each inode stores the attributes and disk block locations of the object's data. [1] File-system object attributes may include metadata (times of last change, [2] access, modification), as well as owner and ...
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.
Therefore, instead of having hard-coded scripts to determine device availability and suitability, Dracut's initramfs depends on the Linux device manager to create symbolic links to device nodes. When the root file system's device node appears, Dracut mounts it as the new root file system.
Loadable kernel modules in Linux are loaded (and unloaded) by the modprobe command. They are located in /lib/modules or /usr/lib/modules and have had the extension .ko ("kernel object") since version 2.6 (previous versions used the .o extension). [5] The lsmod command lists the loaded kernel modules.
