A few minor benefits:
* editors set highliting according to the extensions
* web access to the git repository (github) renders the .asciidoc
files:
* we can link to them from the wiki
* the files are editable via browser and such editations can be
submitted for merge easily

|
*btrfs property* <subcommand> <args>
|
|
|

DESCRIPTION
|
|
-----------
|
|
*btrfs property* is used to get/set/list property for given btrfs object.
|
|
See the description of *get* subcommand for more information about
|
|
both btrfs object and property.
|
|
|
|
*btrfs property* provides an unified and user-friendly method to tune different
|
|
btrfs properties instead of using the traditional method like `chattr`(1) or
|
|
`lsattr`(1).

SUBCOMMAND
|
|
----------
|
|
*get* [-t <type>] <object> [<name>]::
|
|
Gets a property from a btrfs object.
|
|
+
|
|
A btrfs object, which is set by <object>, can be a btrfs filesystem
|
|
itself, a btrfs subvolume, an inode(file or directory) inside btrfs,
|
|
or a device on which a btrfs exists.
|
|
+
|
|
The '-t <type>' option can be used to explicitly
|
|
specify what type of object you meant. This is only needed when a
|
|
property could be set for more then one object type.
|
|
+
|
|
Possible types are 's[ubvol]', 'f[ilesystem]', 'i[node]' and 'd[evice]'.
|
|

|
|
Set the name of property by '<name>'. If no '<name>' is specified,
|
|
all properties for the given object are printed. '<name>' is one of
|
|
the followings.
