i just used parted for the first time (to resize /var).  it was quite
easy to use.  the only snag is that i couldn't get it to use the reiser
libs.  it kept complaining about about library version mismatch.  my
parted version is

ii  parted      1.6.2-1      The GNU Parted disk partition resizing progr

and the reiser libs i installed is progsreiserfs-0.3.1-rc3.
Ah, right.  Yura said he was going to send me a patch!  Anyway, you
could try an earlier version of progsreiserfs...

ai, chihuahua.  i didn't know "which direction" i should go in trying
out a new version of progsreiserfs -- upgrade or downgrade.   i wasn't
sure whether i had to hit "the right version" or "a range of right
versions" if you get my drift.

Right version is progsreiserfs- on http://reiserfs.osdn.org.ua or http://reiserfs.linux.kiev.ua

About new version. I'm hope to ship out progsreiserfs-0.3.1 (with smart resizing, bug fixes and some features) soon. And after it will be done, I'm goind to start work on progsreiserfs-1.0 (full featured fsck, and big architecture improvements)

are there any future plans to allow parted to change the start of an
ext2/3 partition?  or is this just not possible for these filesystems?
It is possible, but it requires journalling for crash recovery (eg:
power failure).  I've decided this is definitely worth doing...
it's a special case of a harder problem, which I'm currently thinking
about how to solve.  (i.e. the convertfs problem.  Yes, I am still
thinking about convertfs!)

heh.  linux is just getting more and more featureful.  that's cool!

reiserfs won the "first journaling system in the linus kernel without a
patch" award, so i converted all the partitions of all my systems to
reiserfs.  that took well over 24 hours when you include the time to
make backups.

then, a few months ago i found there's no corresponding "debugfs" for
reiser partitions.  i found this out after deleting an important file
and debugfs told me it couldn't read reiser partitions.  doh!

so then i started to switch all my partitions back to ext3 (by this
time, ext3 support appeared in the unpatched linus kernels).  i like
being able to undelete my files if i have to.

convertfs would be a very welcome program!  almost as welcome as lifting
that parted constraint.   ;-)

thanks for the reply (and the software!)
