Description of problem:
The big fat warning at the bottom of the documentation page for "chkconfig"
does NOT apply to xinetd driven services. Running chkconfig on xinetd
services sends a SIGUSR2 to xinetd which causes it to perform a hard
reconfiguration with immediate (!) effects. The "service xinetd restart" is
NOT necessary.

Version-Release number of selected component (if applicable):
rhl-cg(EN)-7.2-HTML-RHI (2001-08-30T14:29-0400)


How reproducible:
Always

Steps to Reproduce:
1. tail -f /var/log/messages
2. chkconfig pop3s off
3. chkconfig pop3s on

Observe how xinetd is sent a SIGUSR2 signal which causes hard
reconfiguration. Service "pop3s" from the example is available immediately.


Additional info: bottom of "man xinetd" covers xinetd hard reconfiguration
via SIGUSR2
