ndsconfig upgrade fails when mount point is designated at /var/opt/novell/eDirectory/data

Get the following error when trying to run ndsconfig upgrade when partition mount
point is designated at /var/opt/novell/eDirectory/data

ndsconfig upgrade

Migrating the eDirectory configuration file "/etc/nds.conf" to the new
configuration file location "/etc/opt/novell/eDirectory/conf/nds.conf"...

ERROR: Unable to check if the directory
"/var/opt/novell/eDirectory/data_upg_bak" already exists. If the directory
exists, delete it and execute `ndsconfig upgrade --config-file /etc/nds.conf`
to restart the upgrade operation.
 - Device or resource busy.
ERROR: ndsconfig return value = 1.

Have reported this condition to Novell Engineering.

For now a workaround is available:
Change mount point of partition to something else such as /var/opt/novell/eDirectory.

Steps to duplicate:
1.  Install edir873 on Sles10sp2 box.
2.  Create a partition (I left default at Reiser) and place mount point at
/var/opt/novell/eDirectory/data
3.  Run nds-install to update 8.8.5 packages
4.  Attempt running "ndsconfig upgrade"

Expected Results:  Same as listed above:
ndsconfig upgrade

Migrating the eDirectory configuration file "/etc/nds.conf" to the new
configuration file location "/etc/opt/novell/eDirectory/conf/nds.conf"...

ERROR: Unable to check if the directory
"/var/opt/novell/eDirectory/data_upg_bak" already exists. If the directory
exists, delete it and execute `ndsconfig upgrade --config-file /etc/nds.conf`
to restart the upgrade operation.
