Description of problem:
uuidd runs '/sbin/chkconfig' in its installation scriplets, but the
package doesn't depend on chkconfig:

[root@rtt5 rpms]# rpm --nogpg -q --scripts -p uuidd-2.17.2-12.el6.s390x.rpm 
preinstall scriptlet (using /bin/sh):
getent group uuidd >/dev/null || groupadd -r uuidd
getent passwd uuidd >/dev/null || \
useradd -r -g uuidd -d /var/lib/libuuid -s /sbin/nologin \
    -c "UUID generator helper daemon" uuidd
exit 0
postinstall scriptlet (using /bin/sh):
/sbin/chkconfig --add uuidd
preuninstall scriptlet (using /bin/sh):
if [ "$1" = 0 ]; then
        /sbin/service uuidd stop > /dev/null 2>&1 || :
        /sbin/chkconfig --del uuidd
fi

[root@rtt5 rpms]# rpm --nogpg -q --requires -p uuidd-2.17.2-12.el6.s390x.rpm | grep chkconfig
[root@rtt5 rpms]#


It causes error messages in some cases:
