+# This is a sample device table file for use with mkfs.jffs2. You can
+# do all sorts of interesting things with a device table file. For
+# example, if you want to adjust the permissions on a particular file
+# you can just add an entry like:
+# /sbin/foobar f 2755 0 0 - - - - -
+# and (assuming the file /sbin/foobar exists) it will be made setuid
+# root (regardless of what its permissions are on the host filesystem.
+#
+# Device table entries take the form of:
+# <name> <type> <mode> <uid> <gid> <major> <minor> <start> <inc> <count>
+# where name is the file name, type can be one of:
+# f A regular file
+# d Directory
+# c Character special device file
+# b Block special device file
+# p Fifo (named pipe)
+# uid is the user id for the target file, gid is the group id for the
+# target file. The rest of the entried apply only to device special
+# file.
+
+# When building a target filesystem, it is desirable to not have to
+# become root and then run 'mknod' a thousand times. Using a device
+# table you can create device nodes and directories "on the fly".
+# Furthermore, you can use a single table entry to create a many device
+# minors. For example, if I wanted to create /dev/hda and /dev/hda[0-15]
+# I could just use the following two table entries:
+# /dev/hda b 640 0 0 3 0 0 0 -
+# /dev/hda b 640 0 0 3 1 1 1 15

+.SH DESCRIPTION
+The program
+.B mkfs.jffs2
+creates a JFFS2 (Second Journalling Flash File System) file system
+image and writes the resulting image to the file specified by the
+.B -o
+option or by default to the standard output, unless the standard
+output is a terminal device in which case mkfs.jffs2 will abort.
+
+The file system image is created using the files and directories
+contained in the directory specified by the option
+.B -r
+or the present directory, if the
+.B -r
+option is not specified.
+
+Each block of the files to be placed into the file system image
+are compressed using one of the available compressors depending
+on the selected compression mode.
+
+File systems are created with the same endianness as the host,
+unless the
+.B -b
+or
+.B -l
+options are specified. JFFS2 driver in the 2.4 Linux kernel only
+supported images having the same endianness as the CPU. As of 2.5.48,
+the kernel can be changed with a #define to accept images of the
+non-native endianness. Full bi-endian support in the kernel is not
+planned.
+
+It is unlikely that JFFS2 images are useful except in conjuction
+with the MTD (Memory Technology Device) drivers in the Linux
+kernel, since the JFFS2 file system driver in the kernel requires
+MTD devices.
+.SH OPTIONS
+Options that take SIZE arguments can be specified as either
+decimal (e.g., 65536), octal (0200000), or hexidecimal (0x1000).
+.TP
+.B -p, --pad[=SIZE]
+Pad output to SIZE bytes with 0xFF. If SIZE is not specified,
+the output is padded to the end of the final erase block.
+.TP
+.B -r, -d, --root=DIR
+Build file system from directory DIR. The default is the current
+directory.
+.TP
+.B -s, --pagesize=SIZE
+Use page size SIZE. The default is 4 KiB. This size is the
+maximum size of a data node. Set according to target system's memory
+management page size (NOTE: this is NOT related to NAND page size).
+.TP
+.B -e, --eraseblock=SIZE
+Use erase block size SIZE. The default is 64 KiB. If you use a erase
+block size different than the erase block size of the target MTD
+device, JFFS2 may not perform optimally. If the SIZE specified is
+below 4096, the units are assumed to be KiB.
+.TP
+.B -c, --cleanmarker=SIZE
+Write \'CLEANMARKER\' nodes with the size specified. It is not
+normally appropriate to specify a size other than the default 12
+bytes.
+.TP
+.B -n, --no-cleanmarkers
+Do not write \'CLEANMARKER\' nodes to the beginning of each erase
+block. This option can be useful for creating JFFS2 images for
+use on NAND flash, and for creating images which are to be used
+on a variety of hardware with differing eraseblock sizes.
+.TP
+.B -o, --output=FILE
+Write JFFS2 image to file FILE. Default is the standard output.
+.TP
+.B -l, --little-endian
+Create a little-endian JFFS2 image. Default is to make an image
+with the same endianness as the host.
+.TP
+.B -b, --big-endian
+Create a big-endian JFFS2 image. Default is to make an image
+with the same endianness as the host.
+.TP
+.B -D, --devtable=FILE
+Use the named FILE as a device table file, for including devices and
+changing permissions in the created image when the user does not have
+appropriate permissions to create them on the file system used as
+source.
+.TP
+.B -f, --faketime
+Change all file timestamps to \'0\' for regression testing.
+.TP
+.B -q, --squash
+Squash permissions and owners, making all files be owned by root and
+removing write permission for \'group\' and \'other\'.
+.TP
+.B -U, --squash-uids
+Squash owners making all files be owned by root.
+.TP
+.B -P, --squash-perms
+Squash permissions, removing write permission for \'group\' and \'other\'.
+.TP
+.B --with-xattr
+Enables xattr, stuff all xattr entries into jffs2 image file.
+.TP
+.B --with-selinux
+Enables xattr, stuff only SELinux Labels into jffs2 image file.
+.TP
+.B --with-posix-acl
+Enable xattr, stuff only POSIX ACL entries into jffs2 image file.
+.TP
+.B -m, --compression-mode=MODE
+Set the default compression mode. The default mode is
+.B priority
+which tries the compressors in a predefinied order and chooses the first
+successful one. The alternatives are:
+.B none
+(mkfs will not compress) and
+.B size
+(mkfs will try all compressor and chooses the one which have the smallest result).
+.TP
+.B -x, --disable-compressor=NAME
+Disable a compressor. Use
+.B -L
+to see the list of the available compressors and their default states.
+.TP
+.B -X, --enable-compressor=NAME
+Enable a compressor. Use
+.B -L
+to see the list of the available compressors and their default states.
+.TP
+.B -y, --compressor-priority=PRIORITY:NAME
+Set the priority of a compressor. Use
+.B -L
+to see the list of the available compressors and their default priority.
+Priorities are used by priority compression mode.
+.TP
+.B -L, --list-compressors
+Show the list of the available compressors and their states.
+.TP
+.B -t, --test-compression
+Call decompress after every compress - and compare the result with the original data -, and
+some other check.
+.TP
+.B -h, --help
+Display help text.
+.TP
+.B -v, --verbose
+Verbose operation.
+.TP
+.B -V, --version
+Display version information.
+.TP
+.B -i, --incremental=FILE
+Generate an appendage image for FILE. If FILE is written to flash and flash
+is appended with the output, then it seems as if it was one thing.
+
+.SH LIMITATIONS
+The format and grammar of the device table file does not allow it to
+create symbolic links when the symbolic links are not already present
+in the root working directory.
+
+However, symbolic links may be specified in the device table file
+using the \fIl\fR type for the purposes of setting their permissions
+and ownership.
+.SH BUGS
+JFFS2 limits device major and minor numbers to 8 bits each. Some
+consider this a bug.
+
+.B mkfs.jffs2
+does not properly handle hard links in the input directory structure.
+Currently, hard linked files will be expanded to multiple identical
+files in the output image.

+ To use rbtrees you'll have to implement your own insert and search cores.
+ This will avoid us to use callbacks and to drop drammatically performances.
+ I know it's not the cleaner way, but in C (not in C++) to get
+ performances and genericity...
+
+ Some example of insert and search follows here. The search is a plain
+ normal search over an ordered tree. The insert instead must be implemented
+ int two steps: as first thing the code must insert the element in
+ order as a red leaf in the tree, then the support library function
+ rb_insert_color() must be called. Such function will do the
+ not trivial work to rebalance the rbtree if necessary.
