Title:
  Apparmor Disallows Disabling Dhclient Scripts

Status in isc-dhcp package in Ubuntu:
  Triaged
Status in isc-dhcp package in Debian:
  Unknown

Bug description:
  In some cases, it may be desirable to disable dhclient scripts. By
  default /sbin/dhclient-script is used, and some others are allowed by
  the apparmor profile.

  Without Apparmor, disabling hook scripts can be accomplished with
  flags -sf /bin/true, but with apparmor enabled this gets blocked:

  execve (/bin/true, ...): Permission denied

  Unfortunately dhclient doesn't appear to provide any other mechanism
  for disabling hook scripts.
