"partitioning scheme

=head1 SYNOPSIS

B<vrehash>


=head1 DESCRIPTION

This program is designed to be run after the sysadmin has changed the
C<user-dir-bits> or C<user-dir-slices> configuration variables.
It creates a new users directory called C<new.users>, where C<users>
is the configured name of the user directory.
It then traverses the password table, creates a new user directory name
for each user, and moves the user's mail directory to the new
directory name, creating any necessary directories as it goes.
Any alias entries in the password table are copied as-is.


=head1 RETURN VALUE


Returns 1 if any part of the process fails; 0 otherwise.



=head1 NOTES


When the process is completed, a the old users directory will have
been moved to C<backup.users>.
If no errors occurred, you should be able to safely delete this
directory and all its subdirectories.
Check this directory first, though, to ensure that no important files
remain.



=head1 WARNINGS


This program is not particularly careful to clean up after itself if
an error occurs.
If an error occurs, you will have to check the status of the current
directory, the virtual password file, and all the virtual users
subdirectories in both C<users> and C<new.users>.
