Hi,

    It is important to fix some points to clarify.

    At first, "parted" is a binary that interact with the "libparted" 
library to run
    some features about partitions, like:
       * mkfs
       * fsck
       * cp
       * mv
       * resize
       * and others.

    Actually, parted have zero support for Reiser4.

    Why we need Reiser4 support inside parted?

    We need that parted support Reiser4, because our installer actualy a 
hacked version of RedHat anaconda
    uses pyparted that need parted to create the partitions on the FS on 
a new installation.
    (Therefore also RH people and Linux distro that uses anaconda, like 
YellowDog will benefit for this code).

    Therefore, we don't need to resize Reiser4 partitions actually.

    The necessary code is not necessarely complicated, because libraries 
are well written.
    However, I need to understant how Reiser4 do jobs like fsck and mkfs 
and this code
    cannot be a simple or equivalent (system("mkfs.reiser4")).

    It is necessary to use the parted API to do that.

    FTOSX 2004 includes "reiser4" packages, including "libaal", from Sep 
2004.
    (Check ftp://ftp.futuretg.com/pub/FTOSX/FTOSX_Desktop_2004/i386/SRPMS)

    I create some directories, one for parted 1.6.15 (my hacked version) 
and another for (1.6.22), latest one.

    People that want to know more about the internal of this code, can 
browse:
       
ftp://ftp.futuretg.com/pub/Projects/parted+Reiser4/Actual_without_support/parted-1.6.15/doc/TUTORIAL

    I need to update around 111 chapters in six courses, and therefore I 
will dedicate only 1/2 hours per day to move on
    on this matter.

Thanks,
Giovanni.
