Bug Description

Binary package hint: apparmor

ntp cannot create a temp file. In the usr.sbin.ntpd apparmor profile this file set as:
/var/lib/ntp/ntp.drift.TEMP rw,
 but ntp is actually trying to create /var/lib/ntp/drift.TEMP file.

Log entry from my PC:

Thank you for using Ubuntu and taking the time to report a bug. Does adjusting /etc/apparmor.d/usr.sbin.ntpd from:

  /var/lib/ntp/ntp.drift rw,
  /var/lib/ntp/ntp.drift.TEMP rw,

to:

  /var/lib/ntp/*drift rw,
  /var/lib/ntp/*drift.TEMP rw,

and running 'sudo apparmor_parser -r /etc/apparmor.d/usr.sbin.ntpd' fix this for you?

This could be an SRU, but if CDs need to get respun anyway, it would be nice if this made it into release.
