Installing reiser4 tools.

1. Obtain libaal, unpack, and build it

  The latest libaal is available on
  ftp://ftp.namesys.com/pub/reiser4progs/
  
    $ cd libaal-VERSION
    $ ./configure
    $ make
    $ make install # may require root
    $ # add /usr/local/lib to /etc/ld.so.conf if not already there
    $ /sbin/ldconfig # may require root

  Note: The libaal-minimal library (libaal-stand-alone before 1.0.2 version) 
  is installed by default since 1.0.4 version. To get it installed in earlier
  versions (e.g. for the grub support) configure needs some options:

    $ ./configure --enable-libminimal
    (before 1.0.2: $ ./configure --enable-stand-alone --enable-memory-manager)

2. download reiser4progs, unpack, and build them

  The latest reiser4pros are available on
  ftp://ftp.namesys.com/pub/reiser4progs/
 
    $ cd reiser4progs-VERSION
    $ ./configure
    $ make
    $ make install # may require root
    $ # add /usr/local/lib to /etc/ld.so.conf if not already there
    $ /sbin/ldconfig # may require root

  Note: The libreiser4-minimal library (libreiser4-stand-alone before 1.0.2
  version) is installed by default since 1.0.4 version. To get it installed in
  earlier versions (e.g. for the grub support) configure needs some options:

    $ ./configure --enable-libminimal
    (before 1.0.2: $ ./configure --enable-stand-alone)

3. create reiser4 file system

    $ mkfs.reiser4 <path-to-device-or-file>

How to enable the grub support for reiser4.

1. Install as described above libaal-minimal (libaal-stand-alone before 
   1.0.2) and libreiser4-minimal (libreiser4-stand-alone before 1.0.2) 
   libraries.
2. Obtain the grub legacy tarball
   2.1 The grub itself from http://www.gnu.org/software/grub/grub.html and 
       the reiser4 patch for the grub on ftp://ftp.namesys.com/pub/reiser4progs/LATEST_GRUB_PATCH. 
       Apply the patch:

        $ cd grub-VERSION
        $ patch -p1 <grub_patch.diff
        $ aclocal && autoheader && autoconf && automake --add-missing
   2.2 The grub with reiser4 support from ftp://ftp.namesys.com/pub/reiser4progs/LATEST_GRUB.

The reiser4 support is enabled by default, to disable it the the option of
the congifure script --disable-reiser4 can be used.

Note: There are a plenty of options in reiser4progs/configure script to decrease
the amount of the code in the libreiser4-minimal (libreiser4-stand-alone 
before 1.0.2) library (see --disable-* options), however the result size of 
reiser4_stage1_5 in grub does not fit 23,5K size limit now, and probably will 
not anymore, so stage1_5 reiser4 support in grub does not work -- use stage2 
instead.

*********************************************************
WARNING: 
If you created a reiser4 fs with the mkfs version < 1.0.0, first of all run
        debugfs.reiser4 -C device
The layout of the super block backups has been changed, this will convert the 
fs into the new format. Please check the fs with the 
    $ fsck.reiser4 device
after that.
