 ticket: new
 subject: Delay kadmind random number initialization until after fork
 Component: krb5-admin
 Version_Reported: 1.4.4
 Target_Version 1.6
 Tags: pullup

 Delay initialization of the random number generator in kadmind until
 after the fork and backgrounding of the process.  Otherwise, a lack of
 sufficient entropy during the system boot process will delay system
 boot on systems that run each init script in series and that start
 kadmind via an init script.
