... because it will break chkconfig.

[root@apone ~]# rpm -q chkconfig
chkconfig-1.3.20-2
[root@apone ~]# chkconfig  --add nscd
[root@apone ~]# ls /etc/rc*.d/*nscd
/etc/rc0.d/K74nscd  /etc/rc2.d/K74nscd  /etc/rc4.d/K74nscd  /etc/rc6.d/K74nscd
/etc/rc1.d/K74nscd  /etc/rc3.d/K74nscd  /etc/rc5.d/K74nscd
[root@apone ~]# chkconfig --level 345 nscd on
[root@apone ~]# ls /etc/rc*.d/*nscd
/etc/rc0.d/K74nscd  /etc/rc2.d/K74nscd  /etc/rc4.d/S-1nscd  /etc/rc6.d/K74nscd

If you add a:

# Required-Stop:

line with no deps, chkconfig will not make the (invalid) S-1 links, but will set
both the stop and start priority to 50 (as it's using the LSB code.)

I'll fix the devel chkconfig to use the chkconfig: priorities as a starting base
instead of 50/50, but that fix almost certainly won't be backported to
RHEL3/RHEL4, and probably not to FC3/FC4.

The fix for where it creates the S-1 links should be backported to RHEL3/RHEL4,
but not until U3/U7.
