+    <title>libblkid Overview</title>
+    <partintro>
+    <para>
+The libblkid library is used to identify block devices (disks) as to their
+content (e.g.  filesystem type, partitions) as well as extracting additional
+information such as filesystem labels/volume names, partitions, unique
+identifiers/serial numbers, etc.  A common use is to allow use of LABEL= and
+UUID= tags instead of hard-coding specific block device names into
+configuration files.
+    </para>
+    <para>
+The libblkid librray
+was written by Andreas Dilger for the ext2 filesystem utilties, with input
+from Ted Ts'o.  The library was subsequently heavily modified by Ted Ts'o.
+    </para>
+    <para>
+The low-level probing code, topology and partitions support was written
+by Karel Zak. Currently, the library is mainatned by Karel Zak.
+    </para>
+    <para>
+The library is part of the util-linux package since version 2.15 and is
+available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.

+.SH "NAME"
+terminal-colors.d \- Configure output colorization for various utilities
+.SH "SYNOPSIS"
+/etc/terminal-colors\&.d/[[\fIname\fR][@\fIterm\fR]\&.][\fItype\fR]
+.SH "DESCRIPTION"
+Files in this directory determine the default behavior for utilities
+when coloring output.
+
+The
+.I name
+is a utility name.  The name is optional and when none is specified then the
+file is used for all unspecified utilities.
+
+The
+.I term
+is a terminal identifier (the TERM environment variable).
+The terminal identifier is optional and when none is specified then the file
+is used for all unspecified terminals.
+
+The
+.I type
+is a file type.  Supported file types are:
+.TP
+.B disable
+Turns off output colorization for all compatible utilities.
+.TP
+.B enable
+Turns on output colorization; any matching
+.B disable
+files are ignored.
+.TP
+.B scheme
+Specifies colors used for output.  The file format may be specific to the utility,
+the default format is described below.
+.PP
+If there are more files that match for a utility, then the file with the more
+specific filename wins.  For example, the filename "@xterm.scheme" has less
+priority than "dmesg@xterm.scheme".  The lowest priority are those files without a
+utility name and terminal identifier (e.g. "disable").
+
+The user-specific
+.I $XDG_CONFIG_HOME/terminal-colors.d
+or
+.I $HOME/.config/terminal-colors.d
+overrides the global setting.
+
+.SH EXAMPLES
+Disable colors for all compatible utilities:
+.RS
+.br
+.B "touch /etc/terminal-colors.d/disable"
+.br
+.RE
+
+Disable colors for all compatible utils on a vt100 terminal:
+.RS
+.br
+.B "touch /etc/terminal-colors.d/@vt100.disable"
+.br
+.RE
+
+Disable colors for all compatible utils except dmesg(1):
+.RS
+.br
+.B "touch /etc/terminal-colors.d/disable"
+.sp
+.B "touch /etc/terminal-colors.d/dmesg.enable"
+.br
+.RE
+
+.SH DEFAULT SCHEME FILES FORMAT
+The following statement is recognized:
+
+.RS
+.br
+.B "name color-sequence"
+.br
+.RE
+
+The
+.B name
+is a logical name of color sequence (for example "error").  The names are
+specific to the utilities.  For more details always see the COLORS section
+in the man page for the utility.
+
+The
+.B color-sequence
+is a color name, ASCII color sequences or escape sequences.
+
+.SS Color names
+black, blue, brown, cyan, darkgray, gray, green, lightblue, lightcyan
+lightgray, lightgreen, lightmagenta, lightred, magenta, red and yellow
+.SS ANSI color sequences
+The color sequences are composed of sequences of numbers
+separated by semicolons.  The most common codes are:
+.sp
+.RS
+.TS
+l l.
+ 0	to restore default color
+ 1	for brighter colors
+ 4	for underlined text
+ 5	for flashing text
+30	for black foreground
+31	for red foreground
+32	for green foreground
+33	for yellow (or brown) foreground
+34	for blue foreground
+35	for purple foreground
+36	for cyan foreground
+37	for white (or gray) foreground
+40	for black background
+41	for red background
+42	for green background
+43	for yellow (or brown) background
+44	for blue background
+45	for purple background
+46	for cyan background
+47	for white (or gray) background
+.TE
+.RE
+.SS Escape sequences
+To specify control or blank characters in the color sequences,
+C-style \e-escaped notation can be used:
+.sp
+.RS
+.TS
+lb l.
+\ea	Bell (ASCII 7)
+\eb	Backspace (ASCII 8)
+\ee	Escape (ASCII 27)
+\ef	Form feed (ASCII 12)
+\en	Newline (ASCII 10)
+\er	Carriage Return (ASCII 13)
+\et	Tab (ASCII 9)
+\ev	Vertical Tab (ASCII 11)
+\e?	Delete (ASCII 127)
+\e_	Space
+\e\e	Backslash (\e)
+\e^	Caret (^)
+\e#	Hash mark (#)
+.TE
+.RE
+.sp
+Please note that escapes are necessary to enter a space, backslash,
+caret, or any control character anywhere in the string, as well as a
+hash mark as the first character.
+
+For example, to use a red background for alert messages in the output of
+.BR dmesg (1),
+use:
+
+.RS
+.br
+.B "echo 'alert 37;41' >> /etc/terminal-colors.d/dmesg.scheme"
+.br
+.RE
+
+.SS Comments
+Lines where the first non-blank character is a # (hash) are ignored.
+Any other use of the hash character is not interpreted as introducing
+a comment.

+.SH NAME
+libblkid \- block device identification library
+.SH SYNOPSIS
+.B #include <blkid.h>
+.sp
+.B cc
+.I file.c
+.B \-lblkid
+.SH DESCRIPTION
+The
+.B libblkid
+library is used to identify block devices (disks) as to their content (e.g.
+filesystem type) as well as extracting additional information such as
+filesystem labels/volume names, unique identifiers/serial numbers.
+A common use is to allow use of LABEL= and UUID= tags instead of hard-coding
+specific block device names into configuration files.
+.P
+The low-level part of the library also allows to extract information about
+partitions and block device topology.
+.P
+The high-level part of the library keeps information about block devices in a
+cache file and is verified to still be valid before being returned to the user
+(if the user has read permission on the raw block device, otherwise not).
+The cache file also allows unprivileged users (normally anyone other
+than root, or those not in the "disk" group) to locate devices by label/id.
+The standard location of the cache file can be overridden by the
+environment variable BLKID_FILE.
+.P
+In situations where one is getting information about a single known device, it
+does not impact performance whether the cache is used or not (unless you are
+not able to read the block device directly).
+.P
+The high-level part of the library supports two methods to evaluate LABEL/UUID.
+It reads information directly from a block device or read information from
+/dev/disk/by-* udev symlinks.  The udev is preferred method by default.
+.P
+If you are dealing with
+multiple devices, use of the cache is highly recommended (even if empty) as
+devices will be scanned at most one time and the on-disk cache will be
+updated if possible.
+.P
+In some cases (modular kernels), block devices are not even visible until
+after they are accessed the first time, so it is critical that there is
+some way to locate these devices without enumerating only visible devices,
+so the use of the cache file is
+.B required
+in this situation.
+.SH CONFIGURATION FILE
+The standard location of the
+.I /etc/blkid.conf
+config file can be overridden by the environment variable BLKID_CONF.  For more
+details about the config file see
+.BR blkid (8)
+man page.
+.SH AUTHOR
+.B libblkid
+was written by Andreas Dilger for the ext2 filesystem utilties, with input
+from Ted Ts'o.  The library was subsequently heavily modified by Ted Ts'o.
+
+The low-level probing code was rewritten by Karel Zak.

+ * The libfdisk aligns the end of the partitions to make it possible to align
+ * the next partition to the "grain" (see fdisk_get_grain()). The grain is
+ * usually 1MiB (or more for devices where optimal I/O is greater than 1MiB).
+ *
+ * It means that the library does not align strictly to physical sector size
+ * (or minimal or optimal I/O), but it uses greater granularity. It makes
+ * partition tables more portable. If you copy disk layout from 512-sector to
+ * 4K-sector device, all partitions are still aligned to physical sectors.
+ *
+ * This unified concept also makes partition tables more user friendly, all
+ * tables look same, LBA of the first partition is 2048 sectors everywhere, etc.
+ *
+ * It's recommended to not change any alignment or device properties. All is
+ * initialized by default by fdisk_assign_device().
+ *
+ * Note that terminology used by libfdisk is: 
+ *   - device properties: I/O limits (topology), geometry, sector size, ...
+ *   - alignment: first, last LBA, grain, ...
+ *
+ * The alignment setting may be modified by disk label driver.

+ *    - all partitioning operations are based on in-memory data only
+ *
+ * struct fdisk_partition
+ *    - provides abstraction to present partitions to users
+ *    - fdisk_partition is possible to gather to fdisk_table container
+ *    - used as unified template for new partitions
+ *    - the struct fdisk_partition is always completely independent object and

+.SH NAME
+uuid \- DCE compatible Universally Unique Identifier library
+.SH SYNOPSIS
+.B #include <uuid.h>
+.SH DESCRIPTION
+The UUID library is used to generate unique identifiers for objects
+that may be accessible beyond the local system.  This library
+generates UUIDs compatible with those created by the Open Software
+Foundation (OSF) Distributed Computing Environment (DCE) utility
+.BR uuidgen .
+.sp
+The UUIDs generated by this library can be reasonably expected to be
+unique within a system, and unique across all systems.  They could
+be used, for instance, to generate unique HTTP cookies across multiple
+web servers without communication between the servers, and without fear
+of a name clash.

+.SH DESCRIPTION
+The
+.B uuid_generate
+function creates a new universally unique identifier (UUID).  The uuid will
+be generated based on high-quality randomness from
+.IR /dev/urandom ,
+if available.  If it is not available, then
+.B uuid_generate
+will use an alternative algorithm which uses the current time, the
+local ethernet MAC address (if available), and random data generated
+using a pseudo-random generator.
+.sp
+The
+.B uuid_generate_random
+function forces the use of the all-random UUID format, even if
+a high-quality random number generator (i.e.,
+.IR /dev/urandom )
+is not available, in which case a pseudo-random
+generator will be substituted.  Note that the use of a pseudo-random
+generator may compromise the uniqueness of UUIDs
+generated in this fashion.
+.sp
+The
+.B uuid_generate_time
+function forces the use of the alternative algorithm which uses the
+current time and the local ethernet MAC address (if available).
+This algorithm used to be the default one used to generate UUID, but
+because of the use of the ethernet MAC address, it can leak
+information about when and where the UUID was generated.  This can cause
+privacy problems in some applications, so the
+.B uuid_generate
+function only uses this algorithm if a high-quality source of
+randomness is not available.  To guarantee uniqueness of UUIDs generated
+by concurrently running processes, the uuid library uses global
+clock state counter (if the process has permissions to gain exclusive access
+to this file) and/or the
+.B uuidd
+daemon, if it is running already or can be spawned by the process (if
+installed and the process has enough permissions to run it).  If neither of
+these two synchronization mechanisms can be used, it is theoretically possible
+that two concurrently running processes obtain the same UUID(s).  To tell
+whether the UUID has been generated in a safe manner, use
+.BR uuid_generate_time_safe .
+.sp
+The
+.B uuid_generate_time_safe
+is similar to
+.BR uuid_generate_time ,
+except that it returns a value which denotes whether any of the synchronization
+mechanisms (see above) has been used.
+.sp
+The UUID is 16 bytes (128 bits) long, which gives approximately 3.4x10^38
+unique values (there are approximately 10^80 elementary particles in
+the universe according to Carl Sagan's
+.IR Cosmos ).
+The new UUID can reasonably be considered unique among all UUIDs created
+on the local system, and among UUIDs created on other systems in the past
+and in the future.
+.SH RETURN VALUE
+The newly created UUID is returned in the memory location pointed to by
+.IR out .
+.B uuid_generate_time_safe
+returns zero if the UUID has been generated in a safe manner, \-1 otherwise.

+.SH DESCRIPTION
+The
