The proc filesystem (procfs) is a special filesystem in Unix-like operating systems that presents information about processes and other system information in a hierarchical file-like structure, providing a more convenient and standardized method for dynamically accessing process data held in the kernel than traditional tracing methods or direct access to kernel memory.
fstab (after file systems table) is a system file commonly found in the directory /etc on Unix and Unix-like computer systems. In Linux, it is part of the util-linux package. The fstab file typically lists all available disk partitions and other types of file systems and data sources that may not necessarily be disk-based, and indicates how they are to be initialized or otherwise integrated ...
Mounting a file containing a file system via such a loop mount makes the files within that file system accessible. They appear in the mount point directory. A loop device may allow some kind of data elaboration during this redirection. For example, the device may be the unencrypted version of an encrypted file.
Linux-based devices or Linux devices are computer appliances that are powered by the Linux kernel and possibly parts of the GNU operating system. Device manufacturers' reasons to use Linux may be various: low cost, security, stability, scalability or customizability. Many original equipment manufacturers use free and open source software to ...
CephFS was merged into the Linux kernel in 2010. Ceph's foundation is the reliable autonomic distributed object store (RADOS), which provides object storage via programmatic interface and S3 or Swift REST APIs, block storage to QEMU/KVM/Linux hosts, and POSIX filesystem storage which can be mounted by Linux kernel and FUSE clients. Chiron FS ...
in case of a block device systemd-udevd notifies udisksd, and gvfsd and gvfs-udisks2-volume-monitor. [12] The udisks2 daemon udisksd serves as an interface to system block devices, implemented via D-Bus. It handles operations such as querying, mounting, unmounting, formatting, or detaching storage devices such as hard disks or USB thumb drives.
In computing, mount is a command in various operating systems. Before a user can access a file on a Unix-like machine, the file system on the device [1] which contains the file needs to be mounted with the mount command. Frequently mount is used for SD card, USB storage, DVD and other removable storage devices.
sysfs provides functionality similar to the sysctl mechanism found in BSD operating systems, with the difference that sysfs is implemented as a virtual file system instead of being a purpose-built kernel mechanism, and that, in Linux, sysctl configuration parameters are made available at /proc/sys/ as part of procfs, not sysfs which is mounted ...
