Using uuidd
-----------
The uuidd is a solution to guarantee unique time-based UUIDs.  In the
past there was the problem that UUIDs created by libuuid have not been
guaranteed to be unique if you run multiple processes/threads which
create lots of UUIDs simultaneously.  In order to use this daemon you
have to run it with SUID/SGID bit set:

1. Modify your local permissions setting by adding the following
   line to your /etc/permissions.local
   /usr/sbin/uuidd         uuidd:uuidd     6755

2. Set the permissions with
   $ chkstat --set /etc/permissions.local

3. enable the service uuidd either in YaST or with
   $ insserv uuidd

The daemon is designed to run on demand by default, this means
it is started automatically by libuuid when needed and it
terminates by default after 5 minutes of inactivity.
However if you wish to run the daemon permanently you can
set the parameter UUIDD_ON_DEMAND_ONLY in /etc/sysconfig/uuidd
to "no".
Note, the daemon is not needed in general to create time-based
UUIDs, it is only needed to assure the uniqueness of UUIDs
when creating lots of them in a short amount of time.
