-+Aufs2 -- advanced multi layered unification filesystem version 2
-+http://aufs.sf.net
-+Junjiro R. Okajima
-+
-+
-+0. Introduction
-+----------------------------------------
-+In the early days, aufs was entirely re-designed and re-implemented
-+Unionfs Version 1.x series. After many original ideas, approaches,
-+improvements and implementations, it becomes totally different from
-+Unionfs while keeping the basic features.
-+Recently, Unionfs Version 2.x series begin taking some of the same
-+approaches to aufs1's.
-+Unionfs is being developed by Professor Erez Zadok at Stony Brook
-+University and his team.
-+
-+This version of AUFS, aufs2 has several purposes.
-+- to be reviewed easily and widely.
-+- to make the source files simpler and smaller by dropping several
-+  original features.
-+
-+Note: it becomes clear that "Aufs was rejected. Let's give it up."
-+According to Christoph Hellwig, linux rejects all union-type filesystems
-+but UnionMount.
-+<http://marc.info/?l=linux-kernel&m=123938533724484&w=2>
-+
-+Through this work, I found some bad things in aufs1 source code and
-+fixed them. Some of the dropped features will be reverted in the future,
-+but not all I'm afraid.
-+Aufs2 supports linux-2.6.27 and later. If you want older kernel version
-+support, try aufs1 from CVS on SourceForge.
-+
-+
-+1. Features
-+----------------------------------------
-+- unite several directories into a single virtual filesystem. The member
-+  directory is called as a branch.
-+- you can specify the permission flags to the branch, which are 'readonly',
-+  'readwrite' and 'whiteout-able.'
-+- by upper writable branch, internal copyup and whiteout, files/dirs on
-+  readonly branch are modifiable logically.
-+- dynamic branch manipulation, add, del.
-+- etc...
-+
-+Also there are many enhancements in aufs1, such as:
-+- keep inode number by external inode number table
-+- keep the timestamps of file/dir in internal copyup operation
-+- seekable directory, supporting NFS readdir.
-+- support mmap(2) including /proc/PID/exe symlink, without page-copy
-+- whiteout is hardlinked in order to reduce the consumption of inodes
-+  on branch
-+- do not copyup, nor create a whiteout when it is unnecessary
-+- revert a single systemcall when an error occurs in aufs
-+- remount interface instead of ioctl
-+- maintain /etc/mtab by an external command, /sbin/mount.aufs.
-+- loopback mounted filesystem as a branch
-+- kernel thread for removing the dir who has a plenty of whiteouts
-+- support copyup sparse file (a file which has a 'hole' in it)
-+- default permission flags for branches
-+- selectable permission flags for ro branch, whether whiteout can
-+  exist or not
-+- export via NFS.
-+- support <sysfs>/fs/aufs and <debugfs>/aufs.
-+- support multiple writable branches, some policies to select one
-+  among multiple writable branches.
-+- a new semantics for link(2) and rename(2) to support multiple
-+  writable branches.
-+- no glibc changes are required.
-+- pseudo hardlink (hardlink over branches)
-+- allow a direct access manually to a file on branch, e.g. bypassing aufs.
-+  including NFS or remote filesystem branch.
-+- and more...
-+
-+Currently these features are dropped temporary from this version, aufs2.
-+See design/08plan.txt in detail.
-+- test only the highest one for the directory permission (dirperm1)
-+- show whiteout mode (shwh)
-+- copyup on open (coo=)
-+- nested mount, i.e. aufs as readonly no-whiteout branch of another aufs
-+  (robr)
-+- statistics of aufs thread (/sys/fs/aufs/stat)
-+- delegation mode (dlgt)
-+  a delegation of the internal branch access to support task I/O
-+  accounting, which also supports Linux Security Modules (LSM) mainly
-+  for Suse AppArmor.
-+- intent.open/create (file open in a single lookup)
-+
-+Features or just an idea in the future (see also design/*.txt),
-+- reorder the branch index without del/re-add.
-+- permanent xino files for NFSD
-+- an option for refreshing the opened files after add/del branches
-+- 'move' policy for copy-up between two writable branches, after
-+  checking free space.
-+- O_DIRECT
-+- light version, without branch manipulation. (unnecessary?)
-+- copyup in userspace
-+- inotify in userspace
-+- readv/writev
-+- xattr, acl
-+
-+
-+2. Download
-+----------------------------------------
-+Kindly one of aufs user, the Center for Scientific Computing and Free
-+Software (C3SL), Federal University of Parana offered me a public GIT
-+tree space.
-+
-+There are three GIT trees, aufs2-2.6, aufs2-standalone and aufs2-util.
-+While the aufs2-util is always necessary, you need either of aufs2-2.6
-+or aufs2-standalone.
-+
-+The aufs2-2.6 tree includes the whole linux-2.6 GIT tree,
-+git://git.kernel.org/.../torvalds/linux-2.6.git.
-+And you cannot select CONFIG_AUFS_FS=m for this version, eg. you cannot
-+build aufs2 as an externel kernel module.
-+If you already have linux-2.6 GIT tree, you may want to pull and merge
-+the "aufs2" branch from this tree.
-+
-+On the other hand, the aufs2-standalone tree has only aufs2 source files
-+and a necessary patch, and you can select CONFIG_AUFS_FS=m. In other
-+words, the aufs2-standalone tree is generated from aufs2-2.6 tree by,
-+- extract new files and modifications.
-+- generate a single patch file from modifications.
-+- generate a ChangeLog file from git-log.
-+- commit the files newly and no log messages. this is not git-pull.
-+
-+Both of aufs2-2.6 and aufs2-standalone trees have a branch whose name is
-+in form of "aufs2-xx" where "xx" represents the linux kernel version,
-+"linux-2.6.xx".
-+
-+o aufs2-2.6 tree
-+$ git clone --reference /your/linux-2.6/git/tree \
-+	http://git.c3sl.ufpr.br/pub/scm/aufs/aufs2-2.6.git \
-+	aufs2-2.6.git
-+- if you don't have linux-2.6 GIT tree, then remove "--reference ..."
-+$ cd aufs2-2.6.git
-+$ git checkout origin/aufs2-xx	# for instance, aufs2-27 for linux-2.6.27
-+				# aufs2 (no -xx) for the latest -rc version.
-+
-+o aufs2-standalone tree
-+$ git clone http://git.c3sl.ufpr.br/pub/scm/aufs/aufs2-standalone.git \
-+	aufs2-standalone.git
-+$ cd aufs2-standalone.git
-+$ git checkout origin/aufs2-xx	# for instance, aufs2-27 for linux-2.6.27
-+				# aufs2 (no -xx) for the latest -rc version.
-+- apply "aufs2-standalone.patch" to your kernel source files.
-+
-+o aufs2-util tree
-+$ git clone http://git.c3sl.ufpr.br/pub/scm/aufs/aufs2-util.git \
-+	aufs2-util.git
-+$ cd aufs2-util.git
-+- no particular tag/branch currently.
-+
-+
-+3. Configuration and Compilation
-+----------------------------------------
-+For aufs2-2.6 tree,
-+- enable CONFIG_EXPERIMENTAL and CONFIG_AUFS_FS.
-+- set other aufs configurations if necessary.
-+
-+For aufs2-standalone tree,
-+- enable CONFIG_EXPERIMENTAL and CONFIG_AUFS_FS, you can select =m.
-+- edit fs/aufs/config.mk and set other aufs configurations if necessary.
-+
-+And then,
-+- build your kernel (or a module) by "make"
-+- install it and reboot your system
-+- read README in aufs2-util, build and install it
-+
-+
-+4. Usage
-+----------------------------------------
-+At first, make sure aufs2-util are installed, and please read the aufs
-+manual, ./Documentation/filesystems/aufs/aufs.5.
-+$ man -l aufs.5
-+
-+And then,
-+$ mkdir /tmp/rw /tmp/aufs
-+# mount -t aufs -o br=/tmp/rw:${HOME}=ro none /tmp/aufs
-+
-+Here is another example. The result is equivalent.
-+# mount -t aufs -o br=/tmp/rw:${HOME} none /tmp/aufs
-+  Or
-+# mount -t aufs -o br:/tmp/rw none /tmp/aufs
-+# mount -o remount,append:${HOME} /tmp/aufs
-+
-+Then, you can see whole tree of your home dir through /tmp/aufs. If
-+you modify a file under /tmp/aufs, the one on your home directory is
-+not affected, instead the same named file will be newly created under
-+/tmp/rw. And all of your modification to a file will be applied to
-+the one under /tmp/rw. This is called the file based Copy on Write
-+(COW) method.
-+Aufs mount options are described in aufs.5.
-+
-+Additionally, there are some sample usages of aufs which are a
-+diskless system with network booting, and LiveCD over NFS.
-+See sample dir in CVS tree on SourceForge.
-+
-+
-+5. Contact
-+----------------------------------------
-+When you have any problems or strange behaviour in aufs, please let me
-+know with:
-+- /proc/mounts (instead of the output of mount(8))
-+- /sys/module/aufs/*
-+- /sys/fs/aufs/* (if you have them)
-+- /debug/aufs/* (if you have them)
-+- linux kernel version
-+  if your kernel is not plain, for example modified by distributor,
-+  the url where i can download its source is necessary too.
-+- aufs version which was printed at loading the module or booting the
-+  system, instead of the date you downloaded.
-+- configuration (define/undefine CONFIG_AUFS_xxx)
-+- kernel configuration or /proc/config.gz (if you have it)
-+- behaviour which you think to be incorrect
-+- actual operation, reproducible one is better
-+- mailto: aufs-users at lists.sourceforge.net
-+
-+Usually, I don't watch the Public Areas(Bugs, Support Requests, Patches,
-+and Feature Requests) on SourceForge. Please join and write to
-+aufs-users ML.
-+
-+

-+
-+.\" ----------------------------------------------------------------------
-+.SH DESCRIPTION
-+Aufs is a stackable unification filesystem such as Unionfs, which unifies
-+several directories and provides a merged single directory.
-+In the early days, aufs was entirely re-designed and re-implemented
-+Unionfs Version 1.x series. After
-+many original ideas, approaches and improvements, it
-+becomes totally different from Unionfs while keeping the basic features.
-+See Unionfs Version 1.x series for the basic features.
-+Recently, Unionfs Version 2.x series begin taking some of same

-+
-+.\" ----------------------------------------------------------------------
-+.SH MOUNT OPTIONS
-+At mount-time, the order of interpreting options is,
-+.RS
-+.Bu
-+simple flags, except xino/noxino and udba=inotify
-+.Bu
-+branches
-+.Bu
-+xino/noxino
-+.Bu
-+udba=inotify
-+.RE
-+
-+At remount-time,
-+the options are interpreted in the given order,
-+e.g. left to right.
-+.RS
-+.Bu
-+create or remove
-+whiteout-base(\*[AUFS_WH_BASE]) and
-+whplink-dir(\*[AUFS_WH_PLINKDIR]) if necessary
-+.RE
-+.
-+.TP
-+.B br:BRANCH[:BRANCH ...] (dirs=BRANCH[:BRANCH ...])
-+Adds new branches.
-+(cf. Branch Syntax).
-+
-+Aufs rejects the branch which is an ancestor or a descendant of another
-+branch. It is called overlapped. When the branch is loopback-mounted
-+directory, aufs also checks the source fs-image file of loopback
-+device. If the source file is a descendant of another branch, it will
-+be rejected too.
-+
-+After mounting aufs or adding a branch, if you move a branch under
-+another branch and make it descendant of another branch, aufs will not
-+work correctly.
-+.
-+.TP
-+.B [ add | ins ]:index:BRANCH
-+Adds a new branch.
-+The index begins with 0.
-+Aufs creates
-+whiteout-base(\*[AUFS_WH_BASE]) and
-+whplink-dir(\*[AUFS_WH_PLINKDIR]) if necessary.
-+
-+If there is the same named file on the lower branch (larger index),
-+aufs will hide the lower file.
-+You can only see the highest file.
-+You will be confused if the added branch has whiteouts (including
-+diropq), they may or may not hide the lower entries.
-+.\" It is recommended to make sure that the added branch has no whiteout.
-+
-+Even if a process have once mapped a file by mmap(2) with MAP_SHARED
-+and the same named file exists on the lower branch,
-+the process still refers the file on the lower(hidden)
-+branch after adding the branch.
-+If you want to update the contents of a process address space after
-+adding, you need to restart your process or open/mmap the file again.
-+.\" Usually, such files are executables or shared libraries.
-+(cf. Branch Syntax).
-+.
-+.TP
-+.B del:dir
-+Removes a branch.
-+Aufs does not remove
-+whiteout-base(\*[AUFS_WH_BASE]) and
-+whplink-dir(\*[AUFS_WH_PLINKDIR]) automatically.
-+For example, when you add a RO branch which was unified as RW, you
-+will see whiteout-base or whplink-dir on the added RO branch.
-+
-+If a process is referencing the file/directory on the deleting branch
-+(by open, mmap, current working directory, etc.), aufs will return an
-+error EBUSY.
-+.
-+.TP
-+.B mod:BRANCH
-+Modifies the permission flags of the branch.
-+Aufs creates or removes
-+whiteout-base(\*[AUFS_WH_BASE]) and/or
-+whplink-dir(\*[AUFS_WH_PLINKDIR]) if necessary.
-+
-+If the branch permission is been changing \[oq]rw\[cq] to \[oq]ro\[cq], and a process
-+is mapping a file by mmap(2)
-+.\" with MAP_SHARED
-+on the branch, the process may or may not
-+be able to modify its mapped memory region after modifying branch
-+permission flags.
-+(cf. Branch Syntax).
-+.
-+.TP
-+.B append:BRANCH
-+equivalent to \[oq]add:(last index + 1):BRANCH\[cq].
-+(cf. Branch Syntax).
-+.
-+.TP
-+.B prepend:BRANCH
-+equivalent to \[oq]add:0:BRANCH.\[cq]
-+(cf. Branch Syntax).
-+.
-+.TP
-+.B xino=filename
-+Use external inode number bitmap and translation table.
-+When CONFIG_AUFS_EXPORT is enabled, external inode generation table too.
-+It is set to
-+<FirstWritableBranch>/\*[AUFS_XINO_FNAME] by default, or
-+\*[AUFS_XINO_DEFPATH].
-+Comma character in filename is not allowed.
-+
-+The files are created per an aufs and per a branch filesystem, and
-+unlinked. So you
-+cannot find this file, but it exists and is read/written frequently by
-+aufs.
-+(cf. External Inode Number Bitmap, Translation Table and Generation Table).
-+
-+If you enable CONFIG_SYSFS, the path of xino files are not shown in
-+/proc/mounts (and /etc/mtab), instead it is shown in
-+<sysfs>/fs/aufs/si_<id>/xi_path.
-+Otherwise, it is shown in /proc/mounts unless it is not the default
-+path.
-+.
-+.TP
-+.B noxino
-+Stop using external inode number bitmap and translation table.
-+
-+If you use this option,
-+Some applications will not work correctly.
-+.\" And pseudo link feature will not work after the inode cache is
-+.\" shrunk.
-+(cf. External Inode Number Bitmap, Translation Table and Generation Table).
-+.
-+.TP
-+.B trunc_xib
-+Truncate the external inode number bitmap file. The truncation is done
-+automatically when you delete a branch unless you do not specify
-+\[oq]notrunc_xib\[cq] option.
-+(cf. External Inode Number Bitmap, Translation Table and Generation Table).
-+.
-+.TP
-+.B notrunc_xib
-+Stop truncating the external inode number bitmap file when you delete
-+a branch.
-+(cf. External Inode Number Bitmap, Translation Table and Generation Table).
-+.
-+.TP
-+.B create_policy | create=CREATE_POLICY
-+.TQ
-+.B copyup_policy | copyup | cpup=COPYUP_POLICY
-+Policies to select one among multiple writable branches. The default
-+values are \[oq]create=tdp\[cq] and \[oq]cpup=tdp\[cq].
-+link(2) and rename(2) systemcalls have an exception. In aufs, they
-+try keeping their operations in the branch where the source exists.
-+(cf. Policies to Select One among Multiple Writable Branches).
-+.
-+.TP
-+.B verbose | v
-+Print some information.
-+Currently, it is only busy file (or inode) at deleting a branch.
-+.
-+.TP
-+.B noverbose | quiet | q | silent
-+Disable \[oq]verbose\[cq] option.
-+This is default value.
-+.
-+.TP
-+.B sum
-+df(1)/statfs(2) returns the total number of blocks and inodes of
-+all branches.
-+Note that there are cases that systemcalls may return ENOSPC, even if
-+df(1)/statfs(2) shows that aufs has some free space/inode.
-+.
-+.TP
-+.B nosum
-+Disable \[oq]sum\[cq] option.
-+This is default value.
-+.
-+.TP
-+.B dirwh=N
-+Watermark to remove a dir actually at rmdir(2) and rename(2).
-+
-+If the target dir which is being removed or renamed (destination dir)
-+has a huge number of whiteouts, i.e. the dir is empty logically but
-+physically, the cost to remove/rename the single
-+dir may be very high.
-+It is
-+required to unlink all of whiteouts internally before issuing
-+rmdir/rename to the branch.
-+To reduce the cost of single systemcall,
-+aufs renames the target dir to a whiteout-ed temporary name and
-+invokes a pre-created
-+kernel thread to remove whiteout-ed children and the target dir.
-+The rmdir/rename systemcall returns just after kicking the thread.
-+
-+When the number of whiteout-ed children is less than the value of
-+dirwh, aufs remove them in a single systemcall instead of passing
-+another thread.
-+This value is ignored when the branch is NFS.
-+The default value is \*[AUFS_DIRWH_DEF].
-+.\" .
-+.\" .TP
-+.\" .B rdcache=N
-+.
-+.TP
-+.B rdblk=N
-+Specifies a size of internal VDIR block which is allocated at a time in
-+byte.
-+The VDIR block will be allocated several times when necessary. If your

-+The default value is defined as \*[AUFS_RDBLK_DEF].
-+The size has to be lager than NAME_MAX (usually 255) and kmalloc\-able
-+(the maximum limit depends on your system. at least 128KB is available
