I got many replies and all full of good information. Several folks sent me
various documentation references which were quite useful - apparently the
4.0g and 5.1a docs explain how to do this where the 5.1 docs I have do not.
I am including the reply from Jan Mark Holzer as it was most comprehensive -
several people sent similar information.

Thanks to the many that replied.

Original Question
We have a system that appears to have LSM at least partially configured on
it (vold is running, although according to voldctl is running disabled).
The boot messages also indicate that LSM is starting.  We don't have a
licence for LSM and don't really want it to be running on any of our
servers, but I am unable to find any documentation on how to disable or
uninstall it, or the consequences of trying.  Renaming /sbin/rc3.d/S58lsm to
s58lsm didn't appear to have any affect on reboot.  Any tips?
