Description of problem:

The uuidd service does not create the corresponding (corect) pid file.

Version-Release number of selected component (if applicable):

[root@rstcenter ~]# cat /etc/*release
CentOS release 5.7 (Final)
[root@rstcenter ~]# rpm -qa e2fsprogs
e2fsprogs-1.39-33.el5
[root@rstcenter ~]# rpm -qa uuidd
uuidd-1.39-33.el5

Steps to Reproduce:
1.Start the uuidd service or run the binary
2.Check the pid file created
3.Compare the pid file with the associated pid of the binary
  
Actual results:

[root@rstcenter ~]# ps -efa |grep uuidd
root      4560     1  0 07:49 ?        00:00:00 /usr/sbin/uuidd
[root@rstcenter ~]# cat /var/lib/libuuid/uuidd.pid
4559

Expected results:

4560 (as the associated pid)

Additional info:

Same happens even if you run the service uuidd start command or directly /usr/sbin/uuidd, so it is not a service problem.

Conclusion:

The uuidd binary creates a pid file with 1 integer less than the original pid associated to the process
