Namespaces are a feature of the Linux kernel that partition kernel resources such that one set of processes sees one set of resources, while another set of processes sees a different set of resources. The feature works by having the same namespace for a set of resources and processes, but those namespaces refer to distinct resources.
Operating systems can partition kernel resources by isolated namespaces to support virtualization containers. Similarly, hierarchical file systems organize files in directories. Each directory is a separate namespace, so that the directories "letters" and "invoices" may both contain a file "to_jane".
Unlike the concept of UNIX mount points, where volumes are named and located arbitrarily in a single hierarchical namespace, drive letter assignment allows multiple highest-level namespaces. Drive letter assignment is thus a process of using letters to name the roots of the "forest" representing the file system; each volume holds an independent ...
GNU Parted (from GNU partition editor) is a free partition editor, used for creating and deleting partitions. This is useful for creating space for new operating systems, reorganising hard disk usage, copying data between hard disks, and disk imaging. It was written by Andrew Clausen and Lennert Buytenhek.
A fileset is a sub-tree of the file system namespace and provides a way to partition the namespace into smaller, more manageable units. Filesets provide an administrative boundary that can be used to set quotas and be specified in a policy to control initial data placement or data migration.
The partition type code for a primary partition can either correspond to a file system contained within (e.g., 0x07 means either an NTFS or an OS/2 HPFS file system) or indicate that the partition has a special use (e.g., code 0x82 usually indicates a Linux swap partition).
Here's how to distinguish "sundowning"—agitation or confusion later in the day in dementia patients—from typical aging, from doctors who treat older adults.
The namespace identifier is itself a UUID. The specification provides UUIDs to represent the namespaces for URLs, fully qualified domain names, object identifiers, and X.500 distinguished names; but any desired UUID may be used as a namespace designator.
