Description of problem

1. start a ubuntu 16.04 container

   apiVersion: v1
   kind: Pod
   metadata:
   name: test
   annotations:
   io.kubernetes.cri.untrusted-workload: "true"
   spec:
   containers:
   - command:
   - sleep
   - 8h
   image: ubuntu:18.04

2. exec into this pod and install rsyslog and start service

   apt-get update
   apt-get install rsyslog
   service rsyslog start

Expected result

the rsyslog should start successfully

Actual result

the rsyslog start with error

# service rsyslog start
 * Starting enhanced syslogd rsyslogd      

 rsyslog startup failure, child did not respond within startup timeout (60 seconds)
# service rsyslog status
 * rsyslogd is not running

for non kata containers (without annotation io.kubernetes.cri.untrusted-workload: "true"), above rsyslog can be started successfully.
