** Package changed: apparmor (Ubuntu) => ntp (Ubuntu)
** Description changed:
NTPD drift file is not given permission in Apparmor configuration in
"/etc/apparmor.d/usr.sbin.ntpd".
Proper permission should be given to the drift file.
EXPECTED RESULT
No NTPD drift error print in syslog and system doesn't hang.
ACTUAL RESULT
At least on my development PC during heavy compilation whole system freezes
and I need to do a forced shutdown.
PRINT IN SYSLOG
kernel: [ 3613.938660] type=1400 audit(1456152589.274:52): apparmor="DENIED"
