This interface provides information about a block device on
a UNIX-like system. In addition to just providing
information, methods can be invoked to perform operations on
the block device. Objects implementing this interface have
object paths prefixed with /devices/
followed by a sanitized representation of the base name of
their native path. As the D-Bus specification greatly limits
what characters can be used in object paths, this doesn't
necessarily map one to one with the native basename; for
example the native
path /sys/devices/virtual/block/dm-0 will
be represented as /devices/dm_0.
Most methods on this interface take an array of strings
for options that can affect what the method does. Some of
these options are literal strings (such
as noatime) while some are encoded in the
form of a key/value pair (such
as label=).
A general note about properties: the set of values
returned can be expected to grow in the future as both
hardware and operating system capabilities evolve. Care
has been taken to namespace values so applications can
properly fall back (see e.g.
DriveMediaCompatibility)
and export both general and specific properties (such as
IdUsage
vs.
IdType).
In general an empty string in a property means not
set. Since the empty string is not a valid object path we
use the "/" to mean "not set" for object paths.
